HAWK-C

Medium Wave Infrared (MWIR)

The Hawk-C Medium Wave Infrared (MWIR) detector is a compact and lightweight 640 x 512 Mercury Cadmium Telluride (MCT) Integrated Detector Cooler Assembly (IDCA). The detector is designed for high-performance, low-cost imaging in the 3-5 μm waveband.

To reduce size, weight, and power, the MCT (grown by the MOVPE process) is operated warmer than the standard Hawk IDCA, allowing the use of lower-powered coolers and promoting longer engine life.

Hawk-C is available either as an IDCA with a similar electrical interface to Hawk or proximity electronics.

The proximity electronics also provide the IDCA with drive signals and sensitive power supplies.

Medium wave 3 - 5 μm
Small element 16 μm pitch enables miniaturization of the Dewar assembly and optics
High electro-optic performance with low crosstalk, automatic anti-blooming at the pixel level, and excellent sensitivity
Higher operating temperature
- Longer cooler life
- Less in-service support
- Lower through-life cost

Flexible windowing gives enhanced frame rates over selected areas of the array
Variable gain via user-selectable integration capacitors
Snapshot or rolling readout operation
Simple to use with proximity electronics available
