The QS2-IL | 201685 from Gentec-EO is a Hybrid Pyroelectric Detector that has a spectral response of 0.1 μm - 1000 μm. It delivers a maximum average power of 50 mW and has a thermal frequency of 1.6 Hz. This pyroelectric detector has a noise equivalent power of 2 nW (at 630 nm, 5 Hz, 1 Hz bandwidth) and feedback resistance of 100 GOhms. It has a current responsivity of 0.5 μA/W and voltage responsivity of 25 kV/W (at 630 nm, 15 Hz).

The QS2-IL | 201685 operates in current mode and has several IR window options: Quartz (0.2 μm - 3.5 μm), Barium fluoride (0.2 μm - 17.5 μm), Sapphire (0.1 μm - 7.0 μm), Silicon (1.2 μm - 9.0 μm & 22 μm - 100 μm) & AR germanium (1.8 μm - 23 μm (10.6 μm peak)). It has an aperture diameter of 2 mm and requires a DC supply voltage of 5 V. This pyroelectric detector is available in a TO5 package that measures Ø 9.1 mm x 6.4 mm and is ideal for broadband analytical instruments and laser measurement applications.
