Product Profile of Single - Layer Arc [ Slarc]

Astro optics pvt. Ltd. An iso 9001 : 2000 certified company manufactures various types of optical components and anti-reflection coatings [arc`s] are one of them. Single - layer arc are the simplest of all ar coatings, this consists of a single layer of mgf2 on the substrate. Salient features are as follows:

• It is very useful for high index glasses.

• For example, three element camera lens. The lenses are all of high index glasses and exhibit reflections of up to 8% per surface. This means that only 92% of the light would pass through from each surface. At the end of three lenses [and 6 surfaces], less than 70% of the light would pass through the system. This would result in tremendous loss of light, reducing picture clarity and inducing ghost reflections. If all the surfaces are coated with slarc, an average of 95% of light passes through the assembly resulting in much sharper images and no ghost reflections.
