Ophir 3A-IS optical power sensor and AUX-LED accessoryOphir Photonics Group’s 3A-IS optical power sensor, with the AUX-LED self-absorption accessory, is designed to measure the optical power of divergent, narrowband light sources such as lasers and LEDs.

The integrating sphere and photodiode sensor system measures light sources from 350 to 1100 nm. It uses two 40-mm integrating spheres in series and a photodiode detector. The light intensity on the sensor is significantly reduced, allowing measurement of powers up to 3 W.

The AUX-LED accessory is a current-regulated LED source that provides a self-absorption correction when measuring UV LEDs operating in the 365- to 400-nm range. Additional AUX-LED wavelengths are available for specific UV, visible and IR wavelengths.
