The TeraPyro sensor is a compact and highly sensitive device, based on the combination of a high-quality absorbing black coating, paired with a LiTaO3 pyroelectric crystal. The broad absorption range of the coating allows the use of this sensor over a large spectral range (from 0.1 to 30 THz). The high sensitivity and low NEP offer no compromise on performances. A responsivity switch allows to gain in response time for faster measurements.
The integrated, prealigned, high quality THz optics based on AR coated Si-lenses ensures maximized optical coupling to the sensor.
There are also optional highly modular optics allow three configurations: bare sensor (the base configuration), collimated input or focused input with 50 mm working distance. Two lens options are available:
Polymer Optics Set - Two 1" dia. polymer lenses for broadband transmission.
Si-HRFZ integrated focusing objective - High-resistivity Si optics, optimized for QCL emission detection (THz range) - Two 1" dia. Lenses (F/1 and F/2) AR coating at working frequency.
