87-944 25mm Dia. x 30mm FL; Coated; Ge Plano-Convex Lens BBAR 3-12µm

The 87-944 is a 25mm diameter, 30mm focal length plano-convex lens, designed for use in the 3-12µm spectral range. This lens is sourced from Edmund Optics, a leading provider of optical components.

The lens is made from Germanium burnett, a material known for its excellent transmission properties in the infrared spectrum. The plano-convex geometry, where one side is flat and the other is curved, is ideal for collimating or focusing light. The lens has a 90.12mm radius of curvature on the curved side, contributing to a 29.25mm back focal length.

The lens features broadband anti-reflection (BBAR) coatings on both the front and back surfaces. These coatings, identified as 'edm arcedgermanium31', are specifically designed to reduce surface reflections and increase transmission in the 3-12µm range. The lens has a thickness of 2.13mm at the edge and 3mm at the center, providing robustness and durability.
