OPV220

Vertical Cavity Surface Emitting Laser in Pill Package Features • • • • • 850nm VCSEL Technology High thermal stability Low drive current/high output intensity Narrow and concentric beam angle Pill Package with Flat Lens Absolute Maximum Ratings (TA = 25° C unless otherwise noted) Description The OPV220 is a high performance 850nm VCSEL packaged for sensing applications. This product’s combination of features including high speed, high output power and concentric beam make it an ideal transmitter for integration into all types of position sensing equipment. 30 mA Maximum Reverse Voltage 5 Volts Storage Temperature Operating Temperature Soldering Lead Temperature Applications include: ♦ ♦ ♦ ♦ Maximum Forward Peak Current -40 to +125°C -40 to +85° C 260° C for 10 Seconds Max. Continuous Optical Power at 70°C Photoelectric Sensors Light Curtains Position Sensors Encoders 1.1 mW Additional laser safety information can be found on the Optek website. See application #221. Classification is not marked on the device due to space limitations. See package outline for centerline of optical radiance. Operating devices beyond maximum rating may cause devices to exceed rated classification September 2003 Issue 3.2 Optek Technology, Inc.
