Features

Infrared Responsivity Out to 2.2 Micron

Utilizing an extended InGaAs PIN photodiode, this IR photoreceiver is ideal for application from 800 - 2200 nm.

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. 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.

Using Filters and Optical Fiber

Newport offers accessories that can be used to attach a filter or optical fiber to these photoreceivers. For example, a colored glass filter to remove unwanted wavelengths or a neutral-density filter to attenuate the optical power incident on the photodetector can be mounted with the filter holder accessory. Model is an FC fiber adapter that allows an FC-connectorized fiber to be attached in front of these photoreceivers. Both accessories are sold separately and not included with the photoreceiver.
