Every optical surface will experience certain amount of light reflection due to the index difference in comparison with the medium. These unwanted reflections can create ghost images and deteriorate the image quality. Thin film coating consists of single or multilayers will be used to reduce the reflection. Anti reflection coating will be used in Laser scanner windows, Reflex free sight glasses, Low reflection camera windows, Contrast enhancement, Anti glare coated instrument windows and in microelectronic photo lithography to reduce image (substrate) distortions.
Â
Customized anti reflection coating can be designed to meet the reflection requirements over the desired wavelength band on different substrates like BK7, UVFS, Germanium, Silicon, Zinc sulphide.. etc
