PbS Room Temperature Detectors

Wavelength Range 1.0-5.0 µm MWIR; Detector Size 1x1, 2x2 mm; Time Constant <2 µs; Responsivity 9x103, 4.5x103 V/W; Element Resistance 0.1-2.0 MΩ New Infrared Technologies’ (NIT) LEPTON Series of single-pixel VPD PbSe MWIR detectors are available uncooled as well as with integrated TECs (thermoelectric cooling elements), with different geometries, packaging solutions and preamplifier boards. LEPTON Series single-pixel detectors come in two standard sizes: 1 mm × 1 mm or 2 mm × 2 mm. LEPTON Series uncooled single-pixel PbSe MWIR detectors can be ordered packaged in SMD or TO-5 housings (with cap, hermetic) with sapphire window. These detectors are operational at room temperature and don’t require any cooling devices. LEPTON Series cooled single-pixel PbSe MWIR detectors are hermetically packaged in a TO-8 can housing with cap and sapphire window and include one or two thermoelectric cooler (TEC) stages for higher sensitivity as well as a thermistor. A calibration curve for the thermistor is available. NIT’s LEPTON Series also includes two low-noise preamplifier boards that are 5-V-powered via mini-USB connector: The LEPTON ANALOG PREAMP provides rotary switches to manually select the detector biasing voltage (4 steps from 1.25 V to 10 V) as well as the transimpedance gain (4 steps from 104 to 107 V/A). This preamp outputs a ±10 V analog voltage on a BNC connector. The LEPTON PREAMP WITH USB OUTPUT allows to digitally select the values for detector biasing voltage and transimpedance gain via software. Here, the output is a digital 14 Bit signal with a maximum sampling rate of 20 ksps. This preamp also features an analog output for the preamplifier stage on SMB or BNC connector. For more pixels, linear and two-dimensional array MWIR cameras are available from New Infrared Technologies – please refer to the LUXELL series of linear array MWIR cameras and TACHYON series of high-speed imaging MWIR cameras respectively.
