LXS25025 25 mm Dia. UVFS Plano-Convex Lens; EFL=250mm Uncoated
The LXS25025 is a 25 mm diameter Plano-Convex lens made from UV Fused Silica (UVFS) material, sourced from Knight Optical. This lens is uncoated and features an effective focal length (EFL) of 250mm, making it suitable for a wide range of optical applications.
The lens's geometry includes a thickness edge of 1.5mm and a radius of curvature (R1) of 114.6mm. The inner and outer radii are both zero, indicating a planoconvex shape. The lens's spherical design ensures high-quality imaging and light transmission.
The UVFS material, also known as MAL-1965, is a high-purity fused silica that offers excellent transmission in the deep UV range. It is highly resistant to thermal shock and has a low coefficient of thermal expansion, making it an ideal choice for applications that require stability over a wide temperature range.
The lens is designed to work with a wavelength of 587.6nm, and its uncoated surface ensures high light transmission while maintaining a low level of reflection. However, for applications that require lower reflectivity or higher damage threshold, various coatings are available upon request.
