Coherent Inc. (Santa Clara, CA) (Nasdaq: COHR) has introduced a laser pulse energy sensor specifically optimized for use with medical lasers that combines high accuracy, high damage threshold and a large active area. The new J-50MB-IR EnergyMax(TM) Sensor measures laser beam diameters up to 30 mm from 1 mJ to 3J, over the 500 nm to 3 µm spectral range. It is particularly optimized for use with long pulse, infrared lasers, making it compatible with the Holmium (2100 nm), Erbium (2940 nm), Ruby (694 nm) and Nd:YAG (532 nm and 1064 nm) lasers commonly used for hair removal and other aesthetic dermatological treatments and dental procedures.
The J-50MB-IR combines Coherent’s unique MaxBlack™ coating and a large area pyroelectric detector, together with a set of integrated diffusers, to achieve a damage threshold that is five times higher than that available from competitive products. Furthermore, built in spectral compensation delivers an energy measurement accuracy of ±3% over the entire 500 nm to 3 µm spectral range, which is over twice the accuracy of any other sensor available for this wavelength range.
The J-50MB-IR also offers enhanced convenience and flexibility over other sensors. In particular, it is more compact, yet offers a larger active area than other available sensors. This enables it to measure larger beams, and also be used in tight spaces inside of instruments. More details about the J-50MB-IR EnergyMax sensor can be found on our website at www.coherent.com/energymax.
