SLSQ-50.8B-200P 50.8 mm Dia. x 201.1 mm FL; Double-Convex Lens Uncoated
The SLSQ-50.8B-200P is a high-quality double-convex lens, boasting a diameter of 50.8 mm and a focal length of 201.1 mm. This lens is sourced from OptoSigma, a renowned vendor known for their exceptional optical elements.
The lens is crafted from fused silica, a material with the material ID "fused sil mal-1965". This material is chosen for its excellent optical properties, making it an ideal choice for a wide range of applications. The lens is uncoated, offering users the flexibility to apply their own coatings based on their specific needs.
The geometry of the lens is meticulously designed. It features an edge thickness of 2.9 mm and a center thickness of 6.4 mm. The radii of curvature are R1 = 184 and R2 = -184, resulting in a back focal length of 198.9 mm. The lens's effective focal length (EFL) is 201.1 mm, calculated using the formula EFL = (n - 1) * R, where n is the refractive index of the material.
This lens is designed for use at a wavelength of 546.1 nm. It is spherical in shape, a common choice for its simplicity and effectiveness in bending light. The lens is circular in base shape, making it compatible with a wide variety of optical systems.
