The filters exhibit fully dense and amorphous compositions and can maintain optical stability in extreme environmental conditions. The picture below shows a fully dense bragg mirror with a Laser Damage Threshold more than 10 times that of the best Plasma assisted evaporated coating. The mirror survived a NdYAG beam of more than 106 Joules/square meter.
High durability advanced thin film interference filters with low absorbing design to work with high powered laser sources. Customer specified optical characteristics for blocking and transmission bands.
-optically stable/low thermal shift in CWL
-no ‘Burn out’
-operation at high temperature
Brinell Vision filters use sputtered thin film technology to block unwanted radiation rather than layers of cemented absorption glass (as used in traditional filters). This allows the filter to operate at high temperatures without optical drift or complete breakdown.
