MaxBlack Coating and Diffusers

EnergyMax Sensors

These sensors are specically designed for high energy and high peak

power lasers operating at relatively low repetition rates, such as those

based on Nd:YAG, Ruby and Ho:YAG. The J-50MB-YAG sensor can be used

with beams up to 35 mm in diameter and can work at 1064 nm, 532 nm,

355 nm and 266 nm without the need to change or self-calibrate diffusers

or any other accessories. Both sensors combine a MaxBlack coating and

a diffuser to produce superior damage resistance characteristics. This

combination enables operation with lasers that produce either very high

energy per pulse or very high peak uences.

Features

• Very high energy and peak power handling capabilities

• Operate at Nd: YAG fundamental and harmonics, and

throughout the IR

• Enable pulse energy measurements from 1.5 mJ to 3J

• Spectral compensation characteristics built into each unit

• Onboard sensors provide automatic temperature compensation

• No need to either change diffusers during use or perform your

own spectral calibrations
