The laser safety filter type T2K03 is a light gray absorbing mineral glass filter without additional coating and without lamination. The protection is based on absorption of the laser light within the bulk material. In comparison with filter T1K02 this window is approx. 2mm thicker and negligibly darker, but possesses especially within the range 1050-1400nm higher protection levels. The filter Type T1K03 has very good daylight transmission of approx. 66% which is comparable to that of a normal window. Color recognition is unrestricted. The laser protection filter is especially suitable for IR lasers starting from 950nm up to 1400nm. Additionally it protects against Er:YAG and CO2 lasers and in the whole range between 1400 and 2800nm. The laser safety window is CE certified and available in different standard- and customized sizes. Please calculate required protection levels before using laser safety filters and compare with the filter provided.
