OP-2 series

TECHNICAL DATA

High-Sensitivity Optical Power Sensors

Features

• Si, Ge photodiodes

• Spectral range: 250 nm to 1800 nm

• Fiber-optic connector (optional)

• 1000:1 attenuator for measurement to 5 W

(olptional)

These high-sensitivity semiconductor sensors are ideal for CW laser measurements in the nW to

low mW level. They typically saturate in the 10 to 50 mW level, depending upon the model. For

linear operation up to a maximum of 5 Watts, an optional 1000:1 attenuator is used.
