USB-enabled Energy Sensor, 90µJ-100mJ, 10kHz, Diffuse Metallic Coating

Manufacturer's part number :


Manufacturer Coherent


Description :

EnergyMax-USB J-25MT-10KHZ Energy Sensor use a diffuse metallic coating that enables measurements at high and low repetition rates across a wide range of energies, wavelengths and beam sizes. The damage resistance at 532 nm and shorter wavelengths is even greater than the MaxBlack coating. These are great all-purpose sensors for the 190 nm to 2.1 μm region and offer the lowest energy range of our EnergyMax line.
