Technical content
Energy Range 300 nJ to 1 J These sensors incorporate a diffuse metallic coating that enables measurements at high and low repetition rates across a wide range of energies, and wavelengths from 190 nm to 2.1 μm.
FEATURES
- Unique diffuse metallic coating delivers increased damage threshold, allows high repetition rate operation and reduces specular reflectance
- Operate over the entire 190 nm to 2.1 μm range
- Enable pulse energy measurements from 300 nJ to 1 J with high signal-to- noise characteristics
- Measure up to 10 kHz repetition rate
- Direct USB and RS-232 interfaces –
APPLICATIONS
- Medical
- Scientific
- Industrial
- Laser Rep Rates up to 10 kHz
