BICC-25.4/75.0C 25.4 mm Dia. x -72 mm FL; Uncoated; Double-Concave Lens
The BICC-25.4/75.0C is a spherical lens with a base shape of a circle, sourced from the reputable vendor Laser Components. This lens is a double-concave type, featuring two concave surfaces. The lens has a diameter of 25.4 mm and a thickness at the edge of 4.2 mm, while the center thickness is 2 mm. The effective focal length (EFL) of this lens is -72 mm, indicating its diverging nature.
The lens is made of n-BK7 Schott material, a common and high-quality optical glass. The radii of curvature for the first and second surfaces are -75 mm and 75 mm, respectively. The inner and outer radii are both 0, indicating that the lens has no peripheral curvature.
This lens is designed to operate at a wavelength of 633 nm. It does not have any coating, which means it is uncoated. However, users can request coatings according to their specific needs. The lens is currently in stock and more information can be found on the vendor's website.
