Infrared detectors used at the heart of the FTIR spectrophotometer must have the following characteristics: wide spectral response range, high sensitivity, wide frequency bandwidth and good linearity. LASER COMPONENTS offers lithium tantalate pyroelectric detectors that use a metallic black absorber to improve the modulation performance of these devices.
The coating works in a similar fashion to an anti-reflection coating. Data shows that over the spectral range of 2 – 25 microns, 93% of the incident infrared is absorbed. This approach significantly improves the performance of lithium tantalate devices at high frequencies. From our research and production facility in Arizona we supply customers all over the world with these industrial grade thermal detectors.
