The path of the invisible laser radiation can be detected by the detection card. This test card can be used immediately and does not require activation or light charging. The detection cards with wavelengths from 1.5μm-5μm- and 5mμ-20μm are new, they can locate the overall optical path, such as YAG, Er:YAG and CO2 lasers. For both wavelength ranges, LASER COMPONENTS is available in two versions-high-power version and high-power/low-power version.
The high-power version has a photosensitive area of 40mm×52mm and can be used with lasers with power up to 120W/cm² and 50W/cm².
The high-power/low-power version has two photosensitive surfaces, and the size of each photosensitive surface integrated into the conversion card is 40mm×25mm. The total power of the low-power side reaches 8W/cm²; the power of the high-power side is exactly the same as the high-power version.
