The SLSQ-25B-25P is a high-quality double-convex lens offered by OptoSigma, a renowned vendor in the optical industry. This lens, with a diameter of 25.0 mm, is designed for use in various optical systems that require a focal length of 26.7 mm.
The lens is made of fused silica, a material known for its excellent optical properties, including high transparency and resistance to thermal shock. The base shape of the lens is circular, and it features a double-convex geometry, with radii of curvature of 23 mm for both surfaces. This geometry results in a back focal length of 23.3 mm.
The lens's edge thickness is 2 mm, while the center thickness is 9.4 mm, providing robustness and durability. The lens is uncoated, which means it does not have any anti-reflective or other surface coatings. This may be suitable for applications where such coatings are not required or desirable.
The SLSQ-25B-25P is designed to operate at a wavelength of 546.1 nm, making it suitable for a wide range of optical systems. It is currently in stock and available for immediate purchase through the vendor's website.
