The SPC022 is a Plano-Concave Spherical Lens, sourced from the reputable vendor MKS/Newport. This lens boasts a diameter of 25.4 mm and a focal length of -200 mm, making it suitable for a wide range of optical applications. The lens is uncoated, offering users the flexibility to apply their preferred coating based on their specific requirements.
The lens's geometry is meticulously designed, with a thickness edge of 3.21 mm and a thickness center of 2.5 mm. The inner and outer radii are both zero, indicating a circular base shape. The back focal length (BFL) is -201.71 mm, and the effective focal length (EFL) is -200 mm. The lens is fabricated from UVFS material, specifically identified as UVFS Mal-1965.
This lens is designed to operate at a wavelength of 589 nm. The uncoated nature of the lens provides a clear, unaltered view of the optical path, making it an ideal choice for applications where coating might interfere with the desired outcome.
