PC-9-AF1×1-TO39-NW-90 – ENGINEERING SAMPLE

HgCdTe ambient temperature photoconductive detector with anti-fringing

technology

PC-9-AF1×1-TO39-NW-90 is uncooled IR photoconductive detector based on sophisticated HgCdTe heterostructure for the best

performance and stability.

In order to make this detector immune to unwanted optical fringing effects, VIGO developed anti-fringing technology (internal

modification of substrate's surface) and successfully applied it. This results in the fringing 10 – 40 times smaller compared to the standard

IR detector. In order to minimize fringing it is recommended to work with detectors optimized for longer wavelengths and operate below

λpeak.
