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.
