Large Digital Display with Analog Needle Ideal for Laser Tuning
Built-in Wavelength Compensation for Increased Accuracy from 190nm to 11μm
Optical Sensors Provide Excellent Low Power Sensitivity from Visible to Near-IR Wavelengths
Thermopile Sensor is Ideal for High Power Applications from UV to IR
The FieldMate™ laser power meter from Coherent® combines a large digital LCD display and analog meter with advanced digital processing to enable rapid, sensitive laser adjustment. The small, portable design is ideal for moving from lab to lab. The built-in wavelength compensation feature increases measurement accuracy. 1000:1 Attenuator can be connected to #59-979 Visible Detector Head and #59-980 Near-IR Detector Head. The FieldMate™ is fully NIST traceable.
Note: Complete system requires a detector head and laser power meter.
