The laser safety filter Type T01 is an orange absorbing mineral glass filter without additional coating. The protection is based on absorption of the laser light within the bulk material. The filter Type T01 has a daylight transmission of approx. 50%, but despite the orange colour the colour recognition is still good. The laser protection filter is especially suitable for frequency converted Nd:YAG lasers. The filter Type T01 is available in four different frame styles. Please calculate required protection levels before using laser safety filters and compare with the filter provided.
