112-5230E 25.4 mm Dia. x -500 mm FL; Uncoated; Plano-Concave Lens
The 112-5230E is a plano-concave lens, a type of spherical lens, sourced from EKSMA Optics. This lens boasts a diameter of 25.4 mm and a center thickness of 2.6 mm, with the edge being slightly thicker at 3 mm. The lens is designed with an effective focal length (EFL) of -500 mm, making it suitable for a variety of applications that require concave lenses.
The lens's geometry is defined by its inner and outer radii, both of which are 0 in this case, and its radius of curvature (R1), which is -209.1 mm. This specific lens is made from CAF2 (Calcium Fluoride) material, as indicated by the Material ID [caf2 mal-1963]. The wavelength of this lens is 2940 nm.
Notably, this lens is uncoated, which means it does not have any additional layers to enhance its optical properties. While this may limit its performance in certain applications, it can be advantageous in others where specific coatings may interfere with the desired optical outcomes.
