This is a 35-721 Plano-Convex Lens, a high-quality optical component sourced from Edmund Optics. The lens has a diameter of 2.5mm and a focal length of 2.0mm, making it suitable for a wide range of applications that require precise optical manipulation.
The lens is made from n-lasf9 schott, a material known for its excellent optical properties. This material ensures high transmittance and low absorption across a broad spectrum, making the lens ideal for use in systems that operate within the 500-1100nm wavelength range.
The lens features a YAG-BBAR coating on both the front and back surfaces. This coating enhances the lens's performance by reducing surface reflections and increasing transmittance. The YAG-BBAR coating is designed to operate within the 500-1100nm wavelength range, making it a perfect match for the lens's material.
The lens's geometry is another notable feature. It has a thickness of 0.25mm at the edge and 0.8mm at the center. The lens's inner and outer radii are 0, indicating a flat surface on the incident side and a curved surface on the exit side. The radius of curvature of the exit surface is 1.7mm, and the back focal length is 1.57mm.
