11-697 12.7mm Diameter x 200mm FL; Uncoated; IR Ultrafast Thin PCX Lens
The 11-697 is a 12.7mm diameter, plano-convex lens with a focal length of 200mm, making it suitable for applications that require a long focal length. This lens is sourced from Edmund Optics, a reputable vendor known for their high-quality optical components.
The lens is uncoated, which means it does not have any anti-reflective coatings. While this may result in a higher reflectance loss, it can be advantageous in certain applications where the user wants to control the phase of the light. The lens is made of UVFS Mal-1965, a material with excellent transmission properties in the ultraviolet, visible, and near-infrared regions.
The lens has a spherical shape with a radius of curvature of 91.8mm for the convex surface. The center thickness of the lens is 1.5mm, while the edge thickness is 1.28mm. The back focal length of the lens is 199.19mm, and the effective focal length is the same as the specified focal length, which is 200mm.
The lens is designed for use in the infrared region with a center wavelength of 587.6nm. It is important to note that the lens is not coated, which may affect its performance in high-intensity or high-precision applications. However, its simple design and high-quality material make it a versatile and reliable choice for many optical systems.
