This lens is a type of aspheric lens, which is a category of lens that uses a non-spherical surface to achieve superior optical performance. The base shape of this lens is circular, and it is made from the L-BAL35 material, a type of optical glass developed by Ohara. The lens is designed to operate at a wavelength of 587.6 nm, making it suitable for applications that require high precision at this specific wavelength.

The geometry of the lens is carefully crafted to ensure optimal performance. It has an inner radius of 0, an outer radius of 0, a diameter of 50 mm, and a thickness at the edge of 8.01 mm. The effective focal length (EFL) of the lens is 50 mm, and it has a numerical aperture (NA) of 0.5. The lens is uncoated, which means it does not have any anti-reflective or other coatings applied to its surfaces.

The lens's shape is aspheric, with specific curvature radii (R1 and R2) of 30.85 mm and 500 mm, respectively. The back focal length (BFL) is 38.33 mm, and the thickness at the center of the lens is 19.4 mm. The lens also has a conic constant (K1) of -0.622134, which contributes to its unique optical properties.
