Radiometry Model 2500 Laser Power Attenuator

The model 2500, ideal for laser applications, is a six-inch integrating sphere with 6,000 : 1 attenuation and a 3/4-inch entrance port. The sphere, combined with a silicon sensor, can be used with incident powers of 500 W for pulsed output and 100 W for continuous wave output. It can be used with model 221 and 247 sensor heads.
