36-685 12mm Dia x 84mm FL Uncoated; UV Plano-Convex Lens
The 36-685 is a 12mm diameter, plano-convex lens with a focal length of 84mm, sourced from Edmund Optics. This lens is uncoated and optimized for use with UV light, making it an ideal choice for applications that require high transmission in the UV spectrum.
The lens geometry features a convex surface with a radius of curvature of 38.51mm, resulting in a back focal length of 82.28mm. The edge thickness of the lens is 2.03mm, while the center thickness is 2.5mm, providing a robust and durable design. The lens is made from fused silica, a material with excellent optical properties, including a low coefficient of thermal expansion and high resistance to thermal shock.
The lens is designed for use at a wavelength of 587.6nm, making it suitable for a wide range of applications. Its spherical shape ensures excellent image quality, while its uncoated surface allows for maximum UV transmission.
