Polycarbonate laser protective eyewear provide laser safety officers with excellent low cost, lightweight safety solutions but may have slightly lower ODs and visible light transmission (VLT) values than absorbing glass filters or dielectric coated filters.
Absorbing glass filters generally provide higher optical densities, better VLT values but at a slightly higher cost per pair when compared to polycarbonate safety eyewear.
Nanospec coated filters provide precise protection at specific laser wavelengths and also have excellent VLT values. This is accomplished by applying physical vapor deposition (PVD) technology of dielectric materials upon various optically transparent or absorptive substrates. Precise (1/4 wavelength thickness) vapor depositions of alternate HI-LO index of refraction dielectric coatings or films are applied directly to absorptive polycarbonate or glass filter materials. This technology provides laser protection by reflective as well as absorptive properties.
By capitalizing on the desirable absorptive and reflective characteristics of various laser filter technologies Laservision can also bond or laminate two (or more) types of filters together utilizing special optical adhesive lamination technology to extend the spectral protection range of a single type of eyewear filter to cover a broader range of laser wavelengths.
We use an instrument called a spectrophotometer to measure optical densities. The measurements of laser protective filters are recorded over an entire range of wavelengths from which optical density and visible light transmission data is generated to verify the absorptance, reflective or transmissive properties. This information is analyzed and permanently recorded on the eyewear.
