This is a concave-concave spherical lens, model BICC-12.7-10.8-C, sourced from CVI Laser Optics. It is a high-quality optical component designed for use in laser systems and other applications where precise optical control is required.
The lens has a diameter of 12.7 mm and a center thickness of 2 mm. The concave surfaces of the lens have radii of curvature of -10.8 mm and -10 mm, respectively, resulting in a effective focal length (EFL) of -10 mm. This negative EFL indicates that the lens is a diverging lens, which spreads out light rays passing through it.
The lens is made from N-BK7 glass, a common material for optical components due to its excellent optical properties and high damage threshold. This particular lens is uncoated, meaning it does not have any anti-reflective or other coatings applied to its surfaces. This can be advantageous in some applications where the uncoated surfaces can provide better durability or simplify the optical design.
The lens is designed for use at a wavelength of 587.6 nm, making it suitable for use with a wide range of lasers and other light sources operating at this wavelength. It is a laser-grade component, ensuring it meets the high standards of quality and performance required for use in laser systems.
