Read more LENSE TYPE MATERIALS ILLUSTRATION PROPERTIES AND APPLICATIONS Plano-Convex Lens BK7/ Fused Silica/ Sapphire CaF2/other optical glass Positive focus length. Most suitable where one conjugate is more than five times the other, e.g. in sensor applications or for use with near collimated light. Also where both conjugates are on the same side of the lens, e.g. as an add-on lens to increase the numerical aperture. Double-Convex Lens BK7/ Fused Silica/ Sapphire CaF2/other optical glass Most suitable where the conjugates are on opposite sides of the lenses and the ratio of the distances is less than 5:1, e.g. as simple image relay components. Plano-Concave Lens BK7/ Fused Silica/ Sapphire CaF2/other optical glass Negative lens with the form most suitable where one conjugate is more than five times the other, e.g. producing divergent light from a collimated input beam. Double-Concave Lens BK7/ Fused Silica/ Sapphire CaF2/other optical glass Negative lens with the form most suitable to producing divergent light or a virtual image, where the input light is converging. Positive Meniscus Lens BK7/ Fused Silica/ Sapphire CaF2/other optical glass These lenses may be used to increase the numerical aperture of a positive lens assembly, without an undue increase in the aberrations. Negative Meniscus Lens BK7/ Fused Silica/ Sapphire CaF2/other optical glass These lenses may be used to increase the numerical aperture of a positive lens assembly, without an undue increase in the aberrations.
