Hybrid Quadrant Photodiode Amplifier

Phresh Photonics' Quadrant Photodiode Hybridized with Amplifiers. A quad photodiode amplifier hybrid

Phresh Photonics’

SiQu50-TIA

is a hybrid of a Silicon Quadrant Photodiode combined with four high speed, low noise Trans- Impedance Amplifiers (TIA) all in a small footprint package.

This module can be used to very accurately determine the location and position of a light beam and its movement.

Alternative versions of this Quadrant Photodiode Amplifier with smaller / UV enhanced quads are also available as well as custom configurations. Also available is a Dual Power-Supply version!

Typical applications include laser beam alignment (including in a feedback loop) and target acquisition.
