At the heart of the Single Point Detector Series is a low-noise reamplifier circuit with a 24-bit A/D digital converter. The Single Point Detector can be customized with a range of detectors from Deep UV to the Far IR (200 nm - 14 um). These detectors can support cooled detectors as well as synchronization with external events. Single Point Detectors can receive a trigger from external sources and also be triggered. The software controls also support user-programmed digital I/O. The Ocean Optics Single Point Detectors include software and a software development kit for users who write their own applications. Features - Included software and software development kit - Several triggering modes supported - Integrated temperature control for TE cooled detectors - Low noise amplifier and 24 bit A/D converter - Integrated dark level offset to increase dynamic range for high-background measurements Technical Tip Accessories for Your Mid-IR Systems Most Ocean Optics light sources, optical fibers and sampling accessories transmit light from the UV to the Shortwave NIR – from about 200-2000 nm. For measurements at longer wavelengths, you’ll need accessories constructed with IRresponsive materials such as sapphire, fluoride, chalcogenide and zinc selenide. Some of your options are listed in the table below. For additional information, consult an Ocean Optics Applications Scientist.

ANIR Sectrometers The ANIR series of scanning Fourier Transform Spectrometers (FTS) uses an exclusive micro-actuated lamellar grating and operates with a single photodiode detector. The actuation of the interferometer system is actively controlled by a laser enabling a precise and reliable operation. The single photodiode detection ensures highest dynamic range and signal quality at very attractive pricing.

The modular concept of the ANIR allows users to adapt it for specific applications, as the wavelength range is solely dependent on the detector choice. Features - Extensive wavelength range (three models covering 900-4500 nm) - High resolution of 8 cm -1 - Optional parameters available such as variable gain, resolution and scan speed - High throughput and signal to noise ratio - Low power consumption and reliable operation Sample Applications - Food analysis - Gas detection - Environmental monitoring - Material identification - Process control - Laser characterization About Fourier Transform Spectroscopy (FTS) A Fourier Transform spectrometer is the instrument of choice for high-resolution atomic and molecular spectroscopy. A Fourier Transform is a mathematical operation that transforms (or decomposes) a signal into a set of trigonomic functions. In the case of a spectrometer, Fourier Transform converts raw data into a spectrum via a technique of collecting spectra based on measurements of the coherence of a radiative source, using timeor space-domain measurements of radiation. This technique uses the Wiener-Khinchin theorem, a theorem useful for analyzing the response of Linear Time Invariant (LTI) systems to an arbitrary input signal. As a result, an FTS spectrometer is more sensitive and requires a much shorter sampling time than the standard types of spectrometers used today. An FTS spectrometer such as the ARCoptix ANIR spectrometer has an interferometric module with scanner for laser-assisted positioning control (pictured) and is perfectly suited for high accuracy transmission measurements of gases and liquids. www.oceanoptics.com Tel: +1 727-733-2447 59
