Coherent has introduced a laser pulse energy sensor specifically optimised for use with medical lasers, combining high accuracy, a high damage threshold and a large active area.
The J-50MB-IR Energymax sensor measures laser beam diameters up to 30mm from 1mJ to 3J over the 500nm to 3um spectral range.
It is particularly optimised for use with long-pulse infrared lasers, making it compatible with the Holmium (2,100nm), Erbium (2,940nm), Ruby (694nm) and Nd:YAG (532nm and 1,064nm) lasers commonly used for hair removal and other aesthetic dermatological treatments and dental procedures.
The J-50MB-IR combines Coherent's Maxblack coating and a large-area pyroelectric detector, together with a set of integrated diffusers, to achieve a high damage threshold.
Built-in spectral compensation delivers an energy measurement accuracy of +/-3 per cent over the entire 500nm to 3um spectral range.
The J-50MB-IR can measure larger beams and can also be used in tight spaces inside instruments.
