UV Fused Silica Biconcave Lenses
With two concave surfaces, biconcave lenses have negative focal length, causing collimated incident light to diverge. and they are ideal for expanding the focal length of an optical system. Bena’s biconcave lenses are offered with various materials, including UV Fused silica, ZnSe, Silicon, Ge, CaF2, MgF2, N-SF10, N-BK7 etc. Bena is specialized in providing customized biconcave lenses with large diameter (up to 700mm) and high precision (RMS ≤ λ @ 632.8nm).
