The 67-954 is a laser grade plano-convex lens, designed and manufactured by Edmund Optics, with a diameter of 25mm and a focal length of 50mm. This lens is specifically coated for 355nm wavelength, making it suitable for laser applications within this range.
The lens is made of fused silica, a high-quality material known for its excellent transmission properties and durability. The plano-convex geometry, where one side is flat and the other is curved, allows for efficient light focusing. The lens has a center thickness of 5.84mm and an edge thickness of 2.13mm, providing a balance between weight and optical performance.
The front and back surfaces of the lens are coated with Edmund Optics' Laser V-Coat 355, a specialized coating that enhances the lens's performance in laser applications. This coating reduces reflection and increases transmission, improving the efficiency and effectiveness of the lens in laser systems.
The lens's geometry includes an inner radius of 0mm and an outer radius of 0mm, indicating a simple, straightforward design. The effective focal length (EFL) is 50mm, which, combined with the lens's diameter, provides a decent field of view and depth of field.
