This is a Plano-Convex Lens, a type of spherical lens, sourced from the reputable vendor Standa. The lens is circular in base shape and is designed for use in the ultraviolet region of the spectrum, specifically at a wavelength of 355 nm.
The lens has a diameter of 38.1 mm and a thickness at the edge of 2.5 mm. The center thickness is significantly greater at 13.5 mm, providing a substantial focal length of 50 mm. The lens's inner radius is 0 mm, and the outer radius is also 0 mm, indicating a uniform curvature.
The lens is uncoated, which means it does not have any additional layers to enhance its optical properties or protect it from environmental factors. This may make it more susceptible to damage or degradation over time, but it can also make it more cost-effective.
The material ID for this lens is UVFS MAL-1965, but the specific properties of this material are not provided in the item data. Therefore, we cannot comment on its refractive index, dispersion, or other relevant optical characteristics.
This lens is in stock and available for immediate purchase. For more information, please refer to the vendor's website at http://www.standaphotonics.com/lenses/plano-convex-lenses.php.
