About CMC Electronics Inc., Displays and Sensors- Type: InGaAs
- Light Spectrum: VIS, NIR, SWIR
CMC Electronics’ 264-339831 series use an InGaAs APD with a low k-factor of 0.2,
with a built-in preamplifier and a thermoelectric cooler (TEC), enabling optimum
signal-to-noise performance.
The APD is coupled to a GaAs FET input transimpedance amplifier (TIA) in a 12-
lead TO-8 package, featuring an integrated thermoelectric cooler (TEC) that allows
for temperature control of the APD and facilitates stabilization of gain and
optimized sensitivity. The internal temperature can be monitored via an
embedded thermal sensor close to the APD.
The module is designed with a 50 Ω output impedance which can be AC- or DCcoupled
and can sustain high optical power exposure with a very fast recovery time
with its integrated overload input protection circuit.
Customizations such as bandwidth tuning, NEP screening, responsivity
optimization and different temperature sensors are available to fit your system
design needs upon request.
