Developed specifically for demanding FTIR and precise LWIR spectroscopy applications, the LN2 detector from VIGO is a viable alternative thanks to its excellent parameters and shorter delivery times.
Most important features of the LN2 Detector
The LN2 detector is widely used in demanding applications requiring exceptional sensitivity and a broad spectral range. Its main applications are FTIR and LWIR spectroscopy, but also sophisticated dispersive analysis. The active element material is optimized for operation at 77 K. It comes in a specially designed flatpack package without a window, allowing for easy self-assembly in LN2 metal dewars. Assembly in Kadel KR163-FSMA2 or KR-323 dewars is available upon request, as is the integration of a temperature sensor. The detector is offered with active area dimensions of 1 mm × 1 mm or 0.25 mm × 0.25 mm. It operates in a wide spectral range up to 21 µm. Custom acceptance angle values can also be provided to meet specific application needs.
Our detectors offer reliable, consistent performance backed by proven specifications and advanced antifringing solutions. With in-house epitaxy capabilities based in the EU, we maintain full control over material quality and production. This also allows us to tailor the detector's wavelength range to meet specific application requirements upon request.
LN2 Detector details: HgCdTe photoconductive infrared detector optimized for operation at 77 K: PC-LN2-16.6-1x1-VFP-NW-50
PC-LN2-16.6-1x1-VFP-NW-50 is a photoconductive IR detector based on HgCdTe heterostructures for optimal performance and stability. This detector is optimized for operation at cryogenic temperatures, typically at 77 K (liquid nitrogen temperature). Its 10% cut-off wavelength (λcut-off) is 18.1 µm and its active area (A) is 1 mm × 1 mm. The detector should operate in optimum bias current (Ib) and voltage readout mode. Performance at low frequencies is reduced due to 1/f noise. The detector is available in an especially designed flatpack package (without a window) for easy self-assembly in LN2 metal dewars. This detector is widely used in demanding applications requiring exceptional sensitivity and wide spectral range.
