Boston Electronics Corporation91 Boylston Street, Brookline, Massachusetts 02445 USA(800)347-5445 or (617)566-3821 fax (617)731-0935www.boselec.comboselec@world.std.comWhen do I need to use a preamp? (and other comments onsignal levels and device saturation)One of the very convenient things about Vigo MCT detectors is that many users will not require a preamplifier but can insteadgo directly into an oscilloscope for display of fast transients, usually laser pulses. When is this the case and when not? Briefly,the answer is, for a CW signal, you probably need a preamp, and for short pulses widely spaced in time, you probably do notneed a preamp.The question relates to saturation levels in the detector. We consider “saturation” to be the point at which the detector outputdeviates from linear by 20%. You might want to choose another percentage deviation from linearity, but the idea remains thesame and in fact, once saturation begins it seems to happen quickly so there will not be a large difference whether we speak of1%, 20% or 50% deviation.Saturation is most easily described NOT in terms of input optical signal but in terms of output electrical signal. For example,for the model PD-10.6-3, we expect output saturation at about 10 millivolts for a CW signal, and at about 600 millivolts for asingle short pulse. These represent the extreme cases. Since few if any users have oscilloscopes that will display a signal of 10millivolts with much deflection on the CRT, those users trying to see a CW signal will pretty much always need a preamp.However, users whose input signals are short and strong (say < 1 µsec and > 5 watts peak) should be able to dispense with theamplifier and go direct to the scope using the PD-10.6-3. A certain amount of experimentation around these levels to optimizethem should be expected.Many users in fact have input waveforms that can be considered neither CW nor “short single shot” pulses. This gets us intothe intermediate “quasi-CW” regime. There are no firm rules here, but some guidance is available from experience:• Many CO 2 lasers are called “pulsed” but are in fact better described as modulated. Duty cycle is in the range of 50%and the modulation frequency is in the kHz region. These should be considered CW sources and a preamp used.• Pulsed lasers with short pulses and duty cycles

Choose the Vigo DR-style “Lab Bench” mount ONLY if (A) it is not too large as-is forthe space it will be used and (B) only if operation at a fixed stable temperature isrequired.2. Choose to do it yourself if the Vigo DR-style mount does not fit the space available or ifyou need to squeeze out the highest sensitivity at any given ambient temperature(maximize delta-T) rather using than a stabilized temperature set point.Do it yourself:The sketch on the following page illustrates an acceptable self fabricated heat sink and how tomount the detector on it.If you make your own heat sink you will also need to supply your own power and controlelectronics for the thermoelectric cooler. The model PID1500 TE cooler controller fromWavelength Electronics (also available from Boston Electronics) is suitable as are other similardevices. Excellent external preamps, AC-coupled to 500 MHz and DC-coupled to 200 MHz aredescribed in a following page. Also external versions of the internal heat sink enclosed preampfrom Vigo are available as external devices and often can be delivered faster than the formerline.Use our Lab Bench Mount:Our Lab Bench Mount consists of a cylindrical heat sink on a stalk with a weighted base. Thereis room inside the heat sink for a preamplifier and we offer a full range of preamps internal to theheat sink. Or the user can use an external preamp. Finally two choices of cooler controller areoffered, one with +/-1C temperature stability (corresponding to ~2.5% stability of detectoroutput) and the other with +/-0.1C temperature stability for ~0.25% output stability.Sketches with dimensions and with details of the available preamps and controllers are attached.

Thermoelectrically-cooled detectors can be kept cooled at a constant temperature during operation. Thebuilt-in thermoelectric cooler requires a supply current much higher than the maxiumum allowable currentused for the thermistor and detector element incorporated in the same package. If the supply current forthe thermoelectric cooler is applied to the thermistor or detector element even momentarily, the thermistorand detector element may be damaged. Sufficient care must be taken when dealing with supply currents.1) HandlingThe Peltier element incorporated in thermoelectically-cooled detectors is susceptible to excessive shocks,drop impacts, and vibrations. Use sufficient care in handling this type of detector.2) Heat SinkWhen operating a TE-cooled detector, always use a heat sink. If the detector is operated without using aheat sink, the detector element temperature will rise due to poor heat dissipation. If heat dissipation isinadequate, the detector element may deteriorate due to high temperature, eventually leading topermanent damage.Always use a heat sink having the specified thermal resistance (2°C/W or less for three-stage TE-cooledMCT; 3°C/W or less for two-stage TE-cooled MCT detectors). The detector’s metal package should besecurely attached to the heat sink. Although the heat capacity required of the heat sink depends on thecurrent consumption of the Peltier element, we recommend using a heat sink with a heat capacity of 2W/°C or better. The heat sink must be capable of dissipating the heat generated by a thermoelectriccooler increasing the header temperature less than a few kelvins. In practice, the radiator plate under thedetector header should be at least 2mm thick.RECOMMENDED MOUNTINGThe detector must be firmly mounted on the heat sink. This can be done by the use of a thin layer of heatconductive epoxy. Alternately, apply silicone grease between the heat sink and the detector’s metalpackage. This improves the coupling efficiency of the heat sink and package, thus reducing the thermalresistance between them.When the detector is installed on the heat sink, be sure not to apply any excessive stress to the package.This may cause cracks or leakage in the package. Do not attach the heat sink to the cap; this may causedehermetization of the detectorBoston Electronics Corporation, 91 Boylston Street, Brookline MA 02445(800)347-5445 or (617)566-3821 * fax (617)731-0935 * boselec@boselec.com * www.boselec.com

IR Measuring Set3.5. Heatsinks for TE-Cooled DetectorsTE-cooled detectors are distributed in TO-8 packages. The package, whichalso includes TE-cooler, should be mounted on a suitable heatsink. TheDR-1 heatsink developed and offered by our company provides optimaldetector cooling and stabilization of its temperature. The heatsink playsalso a role of the preamplifier’s housing. Such construction provides asignificant improving of screening and reducing influence of external noiseson the performance of the detection system. The DR-1 can be easilyattached to all typical blocks of optical measuring systems. The DR-10 typeof increased length has been designed for preamplifiers of bandwidth50MHz – 250 MHz. When equipped with DRB-1 stand, the detecting unitcan be used on any flat surface and its vertical position can be easilyadjusted.

IR Measuring Set4. VPAC and VPDC PreamplifiersVPAC-xx and VPDC-xx preamplifiers take full advantage of all detectors’parameters and provide the best protection against ESD, EMI and humanmistakes. The input stages of all VPAC-xx and VPDC-xx preamplifiershave been built with application of ultra low noise transistors or integratedcircuits. They have been optimally configured and biased to achievemaximal S/N ratio, keeping the remaining parameters (gain, bandwidth,maximal output signal and others) within the required limits.4.1. Noise in AmplifiersTo amplify a small signal deriving from IR detector to the value allowing itsfurther processing, a multi-stage preamplifier is usually needed. A resultantnoise performance of the amplifier (preamplifier) depends in practice on thenoise performance of the first stage. The noise performance is usuallyexpressed as the noise voltage or noise current referred to its input (forvoltage or current mode amps respectively). Input stages of VPAC-xx -VPDC-xx series have been designed towards achieving maximal s/n ratiofor a specific type of detector, taking full advantage of its performance.4.2. Technical DataVPAC-xx series presents AC preamplifiers designed for use withphotovoltaic and photoconductive detectors. VPDC-xx series – DCpreamplifiers cope with photovoltaic detectors. Depending on what type ofIR detector is to be used, we offer specific version of a suitablepreamplifier:VPAC-xx-i and VPDC-xx-i preamplifiers are mounted inside DR-1 orDR-10 heatsink and designated for use with TE-cooled detectors. In thiscase a measuring set must be equipped with STCC or CTTC controller ofthe TE cooler. Building the preamplifier into the heatsink enabled radicalshortening the connections between the detector and the input stage whatresulted in significant lowering of EMI level.The output signal of the preamplifier is available on BNC connector but theremaining signals (supply voltages and driving signals for the TE-cooler’scontroller) come out via 9-pin Canon connectorFor some applications VPAC-xx-s and VPDC-xx-s standing alonepreamplifiers are useful. They are supplied in screened housings equippedP

IR Measuring Setwith BNC connectors for the input and output signals and 9-pin Canonconnectors for the power supply.All preamplifiers require supplying devices of very low noise level at theoutput (like accumulators or especially designed well-filtered powersupplies). For standing alone preamplifiers our PPS Ultra Low NoisePower Supply is recommended.P

VIGO System S.A.Mechanical AccessoriesDR-10B Set: Base (DRB-1) and Heat Sink (DR-10) forWide-Band Preamplifiers (>50 Mhz)Beam Power LimitationsFor devices without immersion lenses continuous workincident beam power must not exceed 100 W/cm 3 and pulsesshorter then 1 µs must not exceed 1 MW/cm 3 .For optically immersed devices continuous work incidentbeam power must not exceed 20 W/cm 3 and pulses shorterthen 1 µs must not exceed 10 kW/cm 3 .Saturation power density depend on a type of the detectorand can be provided upon request.Shaping LeadsAvoid bending the leads at a distance less then 2 mm froma base of the package not to damage the glass seals. Whenshaping the leads, do not exceed the following limits:– Maximal mechanical tension – 0.5 kg for 5 sec– Maximum two right angle bends and three twists at thedistance minimum 6 mm from the base of the packageWhen shaping the leads of the detector, short the leads ofthe detecting element with a special jumper.Soldering LeadsIR Detectors can be easily damaged by excessive heat.Special care should be taken when soldering the leads. Usageof heat sinks is highly recommended. Tweezers can be usedfor this purpose; clamp a lead being soldered at a placebetween the soldering iron and the base of the case. To avoiddestructive influence of ESD and other accidental voltages(deriving for example from a non-grounded soldering iron)(e.g. on PVI-2TE detectors) all rules for handling LSIintegrated circuits should be applied to IR detectors too.DR-1B Set: Base (DRB-1) and Heat Sink (DR-1)Precautions for Use, WarrantyStorageThe following conditions should be fulfilled for the safeand reliable operation of detectors:– Storage temperature: -10ºC ÷ +50ºC– Avoiding ESD; detectors are very sensitive toelectrostatic discharges, therefore they should be storedhaving detection element’s leads shorted by a specialjumper.HandlingWindows of some detectors are made of very soft materialslike ZnSe or BaF 2. Particular attention should be paid to notscratch a surface of the window when some sharp tools arebeing used. A damaged window may entirely degrade thedetector’s performance. Excessive mechanical stress appliedto the package itself or to a device containing the package,may result in permanent damage of the latter.Cleaning WindowKeep the window clean. Use a soft cotton cloth dampedwith isopropyl alcohol and wipe off the surface gently ifnecessary.Mechanical ShocksThe Peltier elements may be damaged by the excessivemechanical shocks and vibrations. Great care isrecommended during all manipulations (including normalexploitation) to avoid the mentioned hazards. Drop impactsagainst a hard base may be particularly dangerous.Heat SinkingThe base of the package must be firmly attached to theheatsink. This can be achieved either by using a thin layer(
