Various types of photodetectors can be used for infrared radiation. They are often based on semiconductors with small bandgap energy, and those for relatively long wavelengths often need cryogenic operation conditions. These detectors are crucial for applications in astronomy, defense, and industrial process monitoring.
Some aspects to consider before buying infrared detectors: sensitivity, spectral range, response time, cooling requirements, power consumption, size and weight, environmental resistance, compatibility with systems, maintenance needs.

Gentec Electro-Optics, Inc. 445 St-Jean-Baptiste, Suite 160 Quebec, QC Canada G2E 5N7
Gentec Electro-Optics has pyroelectric thermal detectors with active areas from 1 to 9 mm diameter. They are suitable for room temperature operation with broad spectral response, high sensitivity and high speed (sub-nanosecond response times).
Our Amplified MCT™ is a natural fit with DRS Daylight’s pulsed mid-IR lasers. It is a fully integrated receiver with embedded IR detector, low-noise amplifier, and temperature controller into one compact package.
Features:
room-temperature operation, with a two-stage TEC for cooling to 245 K
broad mid-IR spectral response of 4–12 µm
high sensitivity, with D* > 2.5 × 109 cm·Hz½/W
rise time <3 ns
active area of 1 mm × 1 mm
wide field of view: 78°
AC-coupled photoconductive configuration for pulsed laser detection
Ultrafast photodetectors from ALPHALAS are suitable for measuring optical waveforms with rise times starting from 10 ps and spectral coverage for the IR region up to 2600 nm have bandwidths from DC up to 30 GHz. Available configurations include free-space, fiber receptacle or SM-fiber-pigtailed options and have compact metal housings for noise immunity. For maximum flexibility, most models are not internally terminated. A 50 Ohm external termination supports the highest speed operation, while a high impedance load generates large amplitude signals.
Applications include pulse form and pulse width measurement, laser synchronization, mode beating monitoring and heterodyne measurements. Balanced photodiodes complement the large selection for these models.
Our D2250’s are based upon a new measuring paradigm where mid-infrared light is converted into near-visible light and then measured with conventional near-visible light detector technology.
