G313210000 10 mm Dia. N-BK7 Double-Concave Lens; EFL=-10mm Uncoated

This is a G313210000 10 mm Dia. N-BK7 Double-Concave Lens, with a effective focal length (EFL) of -10mm, making it a concave-concave lens. The lens is sourced from Qioptiq Photonics, a renowned vendor in the field of precision optics.

The lens is made of N-BK7, a popular glass type in the optical industry, known for its excellent optical properties. The lens has a diameter of 10mm and a center thickness of 1mm. The inner and outer radii are both 0, indicating a symmetrical concave shape.

The lens is designed to operate at a wavelength of 588nm. It is uncoated, which means it does not have any anti-reflective or other coatings. This can be beneficial in certain applications where the natural properties of the glass are desired, but it may also increase the risk of unwanted reflections.

The lens is spherical in shape, which is a common geometry for optical lenses. The radii of curvature for the two surfaces are -10.669mm and 10.669mm respectively, indicating a double-concave design.
