Silicon and Germanium Diode Versions

Utilizing both UV-Extended Silicon and Germanium, there is a model covering wavelengths from 190 to 1750 nm for your application.

Adjustable Gain Settings

The three-setting gain adjustment allows you to keep your signal from going off scale while you’re adjusting your experiment or measurement. You can choose a 50-Ω or 10-kΩ load resistor, or you can select the open-circuit setting and provide whatever load resistor you like.

Compact Housing

The compact housing lets you slide the photoreceiver in wherever you need to quickly check your signal, even between closely spaced optics. Since all switches and connectors are located on the top of the housing, you won’t have to worry about access or about cables that drag on the table and block your beam.

Battery Powered

These photoreceivers are battery powered so you’ll need only a single coaxial cable to connect the photodetector to other instruments. To ensure long battery life, we build these photoreceivers using amplifiers with low-current draws. If you’re unsure about the battery status, the built-in battery check can tell you instantly whether or not the battery is good.
