1.5mJ-3J, 25mm Energy Sensor with MaxBlack coating and IR diffuser (RoHS)

Coherent YAG/Harmonics and IR EnergyMax sensors are specifically designed for use with very high energy/peak power lasers operating at low repetition rates, such as those based on Nd:YAG, Erbium, Ruby and Ho:YAG.  The YAG/Harmonics sensor can operate with laser 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 diffusers or any other accessories.  The J-50MB-IR sensor is similar to the J-50MB-YAG sensor, except that its diffuser is optimized for long pulse lasers that operate between the range of 500 nm and 2940 nm. It is ideal for long pulse Erbium lasers. The J-25MB-IR sensor has a 25 mm diameter, and can operate throughout the 694 nm to 2.1 µm wavelength range without any reconfiguration.
