The laser safety filters Type T1K15 (thickness 5mm) and T2K15 (thickness 4,2mm) are light grey absorbing mineral glass filters with an additional reflective coating. The protection is based on absorption and reflection of the laser light. The laser protection filter has an extremely good daylight transmission of approx. 65% which is comparable to that of a normal window. Colour recognition is unlimited. It protects against other Diode, IR- disc-Nd:YAG and CO₂ lasers. Please calculate required protection levels before using laser safety filters and compare with the filter provided.
