Optical filter for industry and medical technology:

UV blockers = UV-blocking filter

UV-blocking filters are used, for example, for skin radiotherapy, lighting at film, photo studios or stage and for night lighting.

The UV-blocking filters are offered in the following materials / thicknesses / sizes:
Borofloat / Float glass / Clear glass 3 mm from 20 x 20 mm to 1,080 x 800 mm
Borofloat / Float glass / Clear glass 4 mm from 20 x 20 mm to 1,080 x 800 mm
Borofloat / Float glass / Clear glass 5 mm from 20 x 20 mm to 1,080 x 800 mm

In addition, we also provide even smaller filter sizes with less material thickness.

We can cut the filters round as well as in any other shape – please see Customised Glass Cutting Service.

 

Application: Skin radiotherapy

UV-blocking filter UB4-420

In certain skin diseases, such as psoriasis and neurodermatitis, defined radiation of the affected skin areas can help to alleviate the disease’s symptoms. UVA rays in the range 315 to 380 nm are particularly effective. At the same time, it is imperative that the skin is not exposed to the more severe UVB and UVC rays. This can be achieved by using UV-absorbing TiO2 in the filters, e.g. FE blue filter type = transmission of UVA and blue light with simultaneous blocking of UVB and UVC radiation.

Application: Lighting

UV-blocking filterr UB4-440

In strong light sources, such as HMI lamps or similar high-pressure metal vapour lamps, UV rays are produced in addition to visible light. For most applications (film/set lighting, photo studio, stage, show), these must be reliably blocked. -> UB4 / UB4-420

Light pollution is increasing by 3% every year. The high blue component of modern LED lighting, in particular, magically attracts insects which then perish in it. Our filters drastically reduce the blue component of the light. For example, lighting on ski slopes requires a reduction in the blue component to protect nocturnal insects.  -> UB4-440 / FM yellow
