11QE65 - Laser Energy Detectors

Laser Energy Detectors
 
Modular Concept
Increase the power capability of your detector with 2 different cooling modules
Low Noise Level
10 µJ for the MT coating
QED Attenuator Available
Measure up to 5X higher energies. Available with optional calibration, all wavelengths between 532 & 1064 nm, or single wavelength
Large Aperture
Effective aperture of 65 x 65 mm
Test Target Included
With the MB models
Smart Interface
