Infrared Filters

In many branches of industry there is a possibility of health hazard because of high level of IR (infrared) radiation. Typical examples are metal-works and glass-works. The basic method of eyes protection is using IR filters. High intensity of IR radiation does not allow for using  absorptive filters because  accumulating light energy causes growing of temperature and destruction  of these kind of filters. The only solution is using reflection filters.
Reflective IR  filters  designed in our company  accommodate demand of European Standard PN-EN 171:2005. Thanks to special optical construction we can make filters in different factors of protection. Now we offer filters with factors: 4-3, 4-4, 4-5, 4-6 and 4-7 which are made of glass or polycarbonate. Face-shields and goggles made of our filters have certificates of Central Institute for Labour Protection in Warsaw.

Below there are examples of transmittance spectrum of  IR filters made  in our laboratory.
