The filter Type T1D01 is a clear absorbing mineral glass filter without additional coating. The protection is based on absorption of the laser light within the bulk material. The filter has an extremely good daylight transmission of approx. 90% which is equal to that of a normal window. Colour recognition is therefore unrestriced. The filter is especially suitable for CO₂ lasers in the wavelength range between 9000 and 1100nm. Additionally it protects against CO or CO₂ lasers at 5400. Please calculate required protection levels before using laser safety filters and compare with the filter provided.
