InAsSb photovoltaic detector


Infrared detector with preamp offering high sensitivity in mid-infrared region (up to 11 μm)


It is a compact infrared detector the integrates an InAsSb photovotaic detector (up to 11 μm) and a preamp. It is approximately 1/200 the the size of previous products, and achieves a response speed of 100 MHz, which is twice as fast. This product is an environmentally friendly infrared detector and does not use lead, mercury, or cadmium, which are substances restricted by the RoHS directive.


- Compact (TO-5)
- High-speed response (DC to 100 MHz)
- RoHS compliant (lead, mercury, cadmium free)


The chip of this product is not sealed and is exposed.
Parts such as electrodes on the chip are not protected by an enclosure or window and so require especially strict care during handling compared to ordinary products.
Before using this product, always read “Precautions / Unsealed products” described below.
