The filters for which the SPLIT SHIELD was originally designed for are coated reflective filters. The special design of the multilayer structure in combination with carefully selected coating materials creates a reflective coating with very high optical density for the laser wavelength or wavelength combination. Due to the small blocking bandwidth of the filter the colour recognition of such filters is signifi cantly improved.
The unrestricted recognition of colours is essential for a lot of applications, especially in the medical market. In addition to the possibility of explicit discrimination of blood and vessels the clear differentiation of coloured instruments or the unconscious perception of signal or warning lights are important aspects in the selection process for laser safety eyewear. That is what the reflective filters in the SPLIT SHIELD frame provide.
