The LA4306-A UVFS Plano-Convex Lens is a high-quality optical component sourced from Thorlabs, a leading vendor in the field of optical equipment. This lens, with a diameter of 1 inch (25.4 mm), is designed for use in the visible spectrum, specifically at a wavelength of 587.6 nm.
The lens is spherical in shape, with a plano-convex base shape. The front surface is convex, while the back surface is planar. The radius of curvature for the front surface is 18.4 mm, and the back focal length is 35.3 mm. The effective focal length of the lens is 40.1 mm. The lens has a center thickness of 7.1 mm and an edge thickness of 2 mm.
The LA4306-A lens is made from UVFS, a material with the material ID "uvfs mal- 1965". This material is known for its excellent optical properties, making it suitable for a wide range of applications.
The lens features anti-reflection coatings on both the front and back surfaces. These coatings, designated as "tho a bbar", are designed to reduce surface reflections and increase transmission in the 350-700 nm wavelength range. This makes the lens ideal for use in systems where high transmission and low loss are critical.
