PASPORT – IR, UV Light, Broad SpectrumInfrared LightPS-2148Ultraviolet LightPS-2149Broad Spectrum LightPS-2150The Infrared sensor uses a Nitrogen filledThermopile with a Tallium Bromide-Iodide(KRS-5) window to sense wavelengthsfrom 580 to 40,000 nm. This allows studentsto measure a variety of phenomenaincluding the infrared radiation emittedfrom theirown hand.Typical ApplicationsA Measure black body radianceA Perform Leslie’s Cube experimentsA Measure Solar radianceA Evaluate heat flow into or out ofthe sensorA Simulate a non-contact temperaturesensorSpecificationsMeasure intensity in Watts/MeterMaximum Sample Rate: 100 HzBuilt-in thermistor to measure temperatureof the “cold” side of the thermopile in °C,°F or KThe Ultraviolet Light Sensor employs afilter to measure the UVA band (315 nm -400 nm). With the UVA filter removed, thesensor detects the visible as well as theUVA. The sensor includes the UVA filter, acollimator, and a sensor handle.Typical ApplicationsA Conduct a sky survey of UV lightA Investigate effectiveness of UVprotection from sunglasses,windows or sunscreen lotions.SpecificationsCollimatorSpectral response of 315 nm to 400 nm(with filter)Photodiode sensing elementMaximum Sample Rate: 1000 HzA For use withSpectrophotometerA Ideal for Black Body SpectrumThe Broad Spectrum Light Sensor isdesigned specifically for use with ourOS-8539 Educational SpectrophotometerSystem and OS-8543 PrismSpectrophotometer Accessory for BlackBody experiments. The Broad SpectrumLight Sensor uses a thermopile and windowcombination that respond to both the nearinfrared and visible light necessary for theBlack Body experiment.Typical ApplicationsA Black Body ExperimentSpecificationsSensing Element: BaF 2 window, xenongas-filled thermopileSpectral Response: 300 to 10,000 nmMaximum Sample Rate: 100 HzScanning the matte surface and cavityof a Leslie’s Cube.The classic textbook diagram of the intensity versuswavelength blackbody curves can be produced withreal data. In this graph, the peak wavelength in theblackbody curve shifts as the source temperature islowered.
