89-426 5mm Dia x 25mm FL VIS 0° Coated; UV Plano-Convex Lens VIS 0° 425-675nm

The 89-426 is a 5mm diameter, 25mm focal length plano-convex lens, designed for use within the visible light spectrum, specifically between 425-675nm. Sourced from Edmund Optics, this lens boasts a standard anti-reflection coating on both the front and back surfaces, ensuring optimal light transmission and minimal loss due to surface reflections.

The lens geometry features a 1.22mm edge thickness and a 1.5mm center thickness, with an outer radius of 0mm and an inner radius of 0mm. The front surface has a radius of curvature of 11.46mm, and the back focal length measures 23.97mm. The lens material is fused silica (mal-1965), a high-quality, low-autofluorescence material well-suited for applications that require minimal background signal and high transmission in the UV, VIS, and NIR spectral ranges.

This plano-convex lens is an excellent choice for a wide range of applications, including imaging, beam shaping, and laser focusing. Its spherical design ensures low spherical aberration, delivering sharp images and high-quality optical performance. With its robust construction and reliable optical characteristics, the 89-426 is an ideal addition to any optical system.
