Large photodetector diameter for easy alignment
Adjustable gain settings
Compact housing for tight spaces
The Large Area Photoreceivers operate from the UV to the IR spectrum for laser or signal detection from 190 to 1750 nm. The large photodetectors used in these designs make alignment easy. You can tweak your experiment without worrying about the beam wandering off the photodetector. Just position the photodetector close to where you think the laser beam is and you’ll see a signal. No more time-consuming and tedious alignment procedures.

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