Designed to produce a highly defined red dot or reticle, facilitating accurate aiming without revealing the location to the target.

Most of Marktech’s standard InGaAs detectors do not have or need an integrated Thermal Electric Cooler (TEC)  because the photodiode already have exceptional responsivity. In many applications, thermoelectric cooling or amplification is not required, which reduces cost and improved overall efficiency. However, TECs, transimpedance amplifiers (TIAs), and other components can be custom packaged with our InGaAs detectors for special applications requiring lower dark current and higher signal to noise (S/N) performance.

Bare and encapsulated LEDs, photodiodes, and other components are assembled on FR4, metal-cored, and flexible circuit boards, ready for production.
