This is a Plano-Convex Lens, a type of spherical lens, sourced from Standa. The lens has a circular base shape and is designed for use with a wavelength of 355 nm. The lens is uncoated, meaning it does not have any additional layers to alter its optical properties.
The lens has a diameter of 12.7 mm and a thickness at the edge of 2.8 mm. The thickness at the center is slightly greater at 3 mm. The effective focal length (EFL) of the lens is 175 mm, which is the distance over which the lens will focus parallel rays of light.
The lens's inner radius is 0, and the outer radius is also 0, indicating a plano-convex shape. The radius of curvature (R1) is 83.313 mm. This information is crucial for understanding how the lens will refract light.
The lens is made from UVFS MAL-1965, a material with specific optical properties suitable for certain applications. The lens's geometry and material make it suitable for use in various optical systems.
