The SLSQ-30-250P is a Plano-Convex lens with a diameter of 30.0 mm and a focal length of 250.0 mm, sourced from the reputable vendor OptoSigma. This lens is made of fused silica, a material known for its excellent optical properties, including high transparency and resistance to thermal shock.
The lens geometry is characterized by its base shape, which is circular, and its geometry, which includes a thickness edge of 2 mm and a thickness center of 3 mm. The effective focal length (EFL) is 250 mm, and the radius of curvature (R1) is 115 mm. The back focal length (BFL) is 248 mm, and both the inner and outer radii are 0 mm.
This lens is uncoated, meaning it does not have any additional layers to enhance its optical properties. However, it is still highly transmissive, particularly in the visible light spectrum, with a wavelength of 546.1 nm.
The SLSQ-30-250P is a Spherical lens, which means it has a spherical surface. This type of lens is commonly used in various optical applications due to its simplicity and versatility.
