SD138-11-38-211

Advanced Photonix has introduced a new silicon detector.

The SD138-11-38-211 features a unique design with two silicon PIN photodiodes vertically integrated into a hermetic TO-5 housing.

The upper photodiode, 300nm-1100nm, absorbs a portion of the incident light, the rest of which reaches the lower photodiode, 950nm-1100nm. The current ratio of the two photodiodes can be used to monitor the colour temperature of an object.

Applications include remote colour temperature sensing and dual wavelength power meters.
