13-467 25mm Dia. CaF2 Aspheric Lens; EFL=50mm; NA=0.25 Uncoated
This is the 13-467 25mm Dia. CaF2 Aspheric Lens, a high-quality optical component sourced from Edmund Optics. The lens boasts an effective focal length (EFL) of 50mm and a numerical aperture (NA) of 0.25, making it suitable for a wide range of optical applications.
The lens is made from Calcium Fluoride (CaF2) with the Mal-1963 material ID, a common choice for its excellent optical properties and durability. The aspheric design, with a base shape of a circle, allows for superior image quality and reduced aberrations compared to traditional spherical lenses.
The geometry of the lens includes an inner radius of 0, an outer radius of 0, a diameter of 25mm, and a thickness at the edge of 4.66mm. The thickness at the center is 8.5mm, and the lens has a back focal length (BFL) of 46.26mm. The aspheric coefficients k1 and k2 are -0.92 and 0, respectively.
The lens is uncoated, offering a cost-effective solution where coating is not critical. However, this may result in reduced transmission and increased susceptibility to environmental factors. Therefore, it's essential to consider the specific requirements of your application when choosing this lens.
