67-235 50mm Dia. x 150mm FL VIS 0° Coated; UV Plano-Convex Lens VIS 0° 425-675nm
The 67-235 is a 50mm diameter x 150mm focal length plano-convex lens, specifically designed for visible light with a 0° angle of incidence. Sourced from Edmund Optics, this lens is coated on both the front and back surfaces with a standard curve, ensuring optimal performance within the specified wavelength range of 425-675nm.
The lens's geometry includes an outer radius of 0mm, an inner radius also of 0mm, and a base shape that is circular. The front surface has a radius of curvature of 68.77mm, while the back focal length measures 145.2mm. The edge thickness is 2.29mm, and the center thickness is 7mm, providing a solid structure for various applications.
The lens material is fused silica (mal-1965), a high-quality, optical-grade material known for its excellent transparency and resistance to thermal shock. This makes the 67-235 suitable for use in environments with extreme temperature fluctuations.
