67-090 12mm Diameter x 18mm FL; Uncoated; Laser Grade PCX Lens
The 67-090 is a spherical lens with a plano-convex base shape and a circular cross-section. This lens, sourced from Edmund Optics, is designed for use in laser applications and boasts a diameter of 12mm and a focal length of 18mm. The lens is uncoated, which can be advantageous in certain applications where a specific coating is not required or desired.
The lens's geometry is meticulously crafted, with a thickness at the edge of 1.41mm and a center thickness of 4mm. The back focal length (BFL) is 15.23mm, and the radius of curvature (R1) is 8.25mm. The lens is made from fused silica, a material with the material ID mal-1965, which is known for its excellent optical properties and durability.
The lens is designed to operate at a wavelength of 587.6nm, making it suitable for a wide range of laser applications. The lack of a coating can make it more versatile, as it can be used in environments where a specific coating might interact unfavorably with other elements. However, it's important to note that uncoated lenses can be more susceptible to damage from environmental factors, so handling and storage should be done with care.
