Laser safety windows T1K03 and T2K03 are light gray absorbing mineral glass filters without additional coating. The protection is based on absorption of the laser light within the bulk material. The laser protection windows offer a very good daylight transmission of approx. 66%, colour recognition is unlimited. Windows T1K03 and T2K03 are especially suitable for IR lasers from 950 nm up to 3000 nm. Additionally they protect against CO2 lasers at 10600 nm. Please calculate required protection levels before using laser safety filters and compare with the filter provided.
