Optical sensor head allows for free-space laser characterisation

January 30, 2018 // By Julien Happich
The AQ2200-232 is a new high-performance optical sensor head which joins Yokogawa’s existing family of optical power meters modules (AQ2200-215 and AQ2200-221) in the company’s modular optical test platform.

The AQ2200-232 sensor head is used in conjunction with the dual-port AQ2200-202 interface module, and is targeted at making accurate measurements in challenging applications such as power testing of laser chips in free space light, I/L curve measurement of laser-diode modules and multicore fibre measurements (with an MPO connector adapter). Key features are a 5mm diameter cooled detector, ideal for measurements in free space, a wavelength measurement range from 800 to 1700nm, and a power measurement range of +15 to -90 dBm. It also offers best-in-class uncertainty of ±1.8%, high stability with constant-temperature control, and a wide single-range power range of 30 dB.
