Yokogawa’s high-performance optical sensor head makes accurate measurements in challenging applications

The new AQ2200-232 from Yokogawa is a high-performance optical sensor head which joins the company’s range of optical power meter modules (AQ2200-215 and AQ2200-221).

Used in conjunction with the dual-port AQ2200-202 interface module, the AQ2200-232 sensor head 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 include 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 uncertainty of ±1.8%, high stability with constant-temperature control, and a wide single-range power range of 30dB.
