Ofil specializes in detection in the Solar Blind UV band (240 - 280 nm) where solar radiation is absorbed by the atmospheric ozone and does not reach earth. The range of "visible" wavelength to which human eyes are senstivie is 400-700nm. Ofil's top quality filters absorb any sun radiation, including background "noise" of solar radiation while transmitting in the narrow UVc band of 240-280nm.

Ofil's unique SBUV filters are designed and manufactured by Ofil and are available incorporated in custome made or in ready made systems.

Ofil's SBUV filters constitute the critical components in fire and flames detection. Ofil's filters are independent of light angle of incidence; can be embedded as part of the optics and have optical curvatures; sustain temperature differences of  40ºC up to 90ºC; and proven record of endurance, serving 5 years in field work without any degradation.

The optic filters are categorized according to the photo-cathode diameter they are used in, and temperature resistance. With optional customization.
