67-233 50mm Dia. x 75mm FL VIS 0° Coated; UV Plano-Convex Lens VIS 0° 425-675nm

The 67-233 is a 50mm diameter, 75mm focal length plano-convex lens, specifically designed for visible light applications with a 0° angle of incidence. Sourced from Edmund Optics, this lens boasts a high-quality fused silica material (fused sil mal-1965) known for its excellent transparency and resistance to thermal shock.

The lens features a standard curvature coating on both the front and back surfaces, using Edmund Optics' vis-0 standard curve. This coating enhances the lens's performance by reducing surface reflections and increasing transmission, particularly within the 425-675nm wavelength range.

The geometry of the lens includes a 1.72mm edge thickness and a 12.5mm center thickness, with an effective focal length (EFL) of 75mm. The inner and outer radii are both 0mm, and the lens's base shape is circular. The front surface has a radius of curvature (R1) of 34.39mm, and the back focal length (BFL) is 66.43mm.

This lens is an excellent choice for applications that require a high-quality, UV-transmitting plano-convex lens with precise specifications. Its compatibility with visible light and UV spectrum, coupled with its robust construction and reliable coating, makes it a versatile and valuable addition to any optical system.
