The DH-InGaAs detectors are the first choice for most applications covering the 900nm to 1700nm range. They can be used in both DC and AC (lock-in amplifier) modes of operation.

For systems requiring frequent change of detectors, a quick-change (type '-QC') housing is available.

Thermo-electrically cooled detectors are offered for use in hostile ambient temperature conditions and for extended wavelength range devices (to 1900nm).
