The SLSQ-30-450P is a Plano-Convex lens with a diameter of 30.0 mm and a focal length of 450.0 mm, sourced from OptoSigma. This lens is made of fused silica, a material known for its excellent optical properties, durability, and resistance to thermal shock.
The lens geometry includes an edge thickness of 2.0 mm and a center thickness of 2.5 mm. The radius of curvature (R1) is 207 mm, and the back focal length (BFL) is 448.3 mm. The lens is uncoated, which means it does not have any anti-reflective or other coatings.
This lens is suitable for applications that require a long focal length and a large diameter. Its uncoated surface makes it ideal for use in environments where coatings might be damaged or where the additional cost of coatings is not justified. The lens is currently in stock and can be purchased directly from the vendor's website.
