Astro optics pvt. Ltd. An iso 9001 : 2000 certified company manufactures various types of optical components and v - coatings are coatings specifically designed for specific wavelengths, used in laser optics. They can be tuned for any required laser wavelength from uv to near ir region. These give reflection < 0.3% per surface.
Multi-layer broadband ar coating for visible region on bk7, average reflection < 0.40% per surface from 415-700nm for 0° incidence angle.
Higher efficiency multi-layer broadband ar coating for visible region on bk7, average reflection <0.25% per surface from 400-700nm for 0° incidence angle.
