Cảm biến đo công suất laser Coherent J-25MB-IR, J-50MB-YAG, J-50MB-IR
The J-50MB-IR is specifically designed for high damage threshold when used with pulsed lasers used in medical procedures such as Erbium and Holmium lasers. It has a damage threshold in excess of 100 J/cm at 2940 nm with a 100 µs pulse width.
YAG/Harmonics and IR Series products are also “smart” sensors, and incorporate onboard electronics to automatically correct for ambient temperature, as well as built-in wavelength compensation factors. These sensors are compatible with Coherent LabMax-TOP, 3sigma, FieldMaxII-TOP, FieldMaxII-P, EPM1000 and EPM2000 meters.
Both sensors accept an optional heatsink, which can be easily attached by the user to extend the maximum energy or average power range. Specifically, these heat sinks allow the J-25MB-IR sensor to be used up to 15 W average power, and the J-50MB-YAG sensor to be used up to 45 W average power.
The following table outlines the average power handling capability of the sensors when used with optional user installable heat sinks.
