A quadrant photodiode is a 2 x 2 array of individual photodiode active areas, separated by a small gap, fabricated on a single chip. This maximizes the uniformity and performance matching between the four individual elements. Quadrant photodiodes are used most frequently for position sensing of laser beams, autocollimators and other alignment applications.
In addition to the devices listed below, Pacific Silicon Sensor can design and manufacture quadrant photodiodes in differing sizes and shapes, enhanced to meet the requirements of your specific application. Our quadrant photodiodes are also available in die form or can be mounted on/in any electronic package or substrate compatible with wire bonding. |
