SKU: UCFSPC-0.5--25.4
MSE PRO™ Uncoated Fused Silica Plano-Concave Lenses, Ø1/2"
MSE supplies offers Ø1/2" Uncoated Fused Silica Plano-Concave Lenses for your optical experiments. Fused Silica is the material used in UV region and imaging applications. It has high transmission from 200nm to 2.5µm. In addition, it also can be used in higher operating temperatures. A plano-concave lens diverges parallel input rays and has a negative focal length. The output rays do not actually meet to form a real focus and appear to be diverging from a virtual spot located on the object side of the lens.
MSE Supplies can offer a variety of optical elements, with different focal length and coating options. Please contact us for customization or bulk orders.
