We offer positive meniscus lenses with different kinds of substrates like BK7, SF4, SF5 and UV fused silica. There are coating options for these lenses, L/4 MgF2, VIS, VIS-NIR, etc. Most of our AR coatings are very durable with resistance to both physical and environmental damage. When specifying an AR coating to suit your application, you need to be fully aware of the spectral range of your optical system.
