The path of invisible laser radiation can be verified using detector cards from Laser Components (Hudson, NH). These cards are ready for immediate application and do not have to be activated or optically charged. The cards for wavelengths from 1.5m to 5m and 5m to 20m can localize the beam path of Hol:YAG, Er:YAG, and CO2 lasers, for example.

Laser Components has two versions available for both wavelength ranges. The high-power versions have an active area of 40 mm x 52 mm and can be used with a laser power of up to 120 W/cm2 and 50 W/cm2. The highpower/ low-power version has two active areas integrated into the converter card, each of which measures 40 mm x 25 mm in size. The lowpower side works up to 8 W/cm2, and the power of the high-power side is identical to that of the high-power version.
