We can manufacture a wide range of filters:
Contrast Filters: used to increase the readability of visible light from displays and monitors. This is done by adapting the contrast filter’s transmittance to the wavelength of the light emitted from the display, so that the secondary light is blocked. The narrower the transmittance curve in the desired wavelenght region, the greater the contrast. The filtering process also means that the amount of reflected light from the surface of the display is so limited that the mechanical components and electronics which lie behind the filter are partially or fully hidden.
It is possible to create a high degree of contrast by either a filter with narrow transmittance curve or a dark tinted filter. The latter will make information from the display stand out clearly against a dark background. This may increase readability and provides an elegant design function.
LCD filters: optical filters used for LCD application with a high transmissivity performances. Our LCD filters are produced in transparent acrylic but with an integrated light guiding material. In this way, it is possible to obtain the same high transmittance as transparent acrylic with high contrast and thus greater readability. Our LCD filters absorbs the sun’s harmful UV rays below 400 nm.
Infrared filters: Infrared filters are used in sensors, security systems, scanners, IR camera, and in all the application where it is necessary to exclude visible light.
Shielding windows: to control electromagnetic interference. Shielding window is a balance between the shielding effect and the light transmission. It is important to reach the required shielding performance with the maximum readability.
Diffusion Filters: used mainly for back-lighted LCD modules, such as passengers information systems at airport and train stations.
Polycarbonate Filters: highly resistant to shock and impacts.
We offer high quality filters as we use the best cast acrylic. Cast acrylic ensures a very regular surface of the optical filter and a minimize the optical imperfections.
We supply different surface treatment solutions:
