BICC-50.8/75.0C 50.8 mm Dia. x -72 mm FL; Uncoated; Double-Concave Lens

The BICC-50.8/75.0C is a spherical lens with a base shape of a circle, sourced from the reputable vendor Laser Components. This particular lens is a double-concave type, featuring two concave surfaces. The lens has a diameter of 50.8 mm and a thickness at the edge of 11.9 mm, while the center thickness is 3 mm. The effective focal length (EFL) of this lens is -72 mm, indicating its diverging nature.

The lens is made from n-BK7 Schott, a high-quality optical glass known for its excellent transparency and low auto-fluorescence. The radii of curvature for the first and second surfaces are -75 mm and 75 mm, respectively. The lens does not come with any coating, as indicated in the item data.

This lens is suitable for use with a wavelength of 633 nm. The item data does not specify any particular coating for this lens, suggesting that it is uncoated. However, users should note that coatings can significantly affect the performance of optical elements, and uncoated lenses may exhibit higher levels of reflection and lower transmission compared to coated ones.
