4.5mm Diameter x 4.5mm FL Plano-Convex Lens with Visible Light Coating
This 4.5mm diameter x 4.5mm focal length plano-convex lens is a product of Edmund Optics, a leading manufacturer of optical components. The lens is designed for use with visible light, with a coating that enhances its performance within the 425-675nm range.
The lens is made from n-lasf44 Schott, a high-quality optical material known for its excellent transmittance and durability. The plano-convex geometry, where one side is flat and the other is curved, allows for efficient light bending and focusing. The lens has a 3.61mm radius of curvature on the curved side, contributing to its focal length of 4.5mm.
The lens's thickness varies from 1.8mm at the edge to 2.59mm at the center, providing a balanced structure for optimal performance. The back focal length is 3.05mm, and the lens has no inner or outer radius, indicating a uniform curvature.
The lens's front and back are coated with the EDM VIS-0 STD CURVE coating, designed to enhance its performance in the visible light spectrum. This coating ensures minimal light loss due to reflection, improving the overall efficiency of the lens.
