L-BCC017 12.5 mm Dia. Double-Concave Lens; EFL=-40mm Uncoated
The L-BCC017 is a spherical lens with a base shape of a circle, sourced from the reputable vendor Ross Optical. This lens falls under the category of a bi-concave lens, characterized by its double-concave structure. The lens has a diameter of 12.5 mm and a thickness at the edge of 2.5 mm, while the center thickness measures 1.5 mm.
The effective focal length (EFL) of this lens is -40 mm, indicating that it is a diverging lens, causing incoming light rays to spread out. This property makes it suitable for applications where light needs to be dispersed, such as in cameras, projectors, or other optical instruments.
The lens is made from the material n-bk7 schott, a popular choice in the optical industry due to its excellent optical properties. The wavelength for this lens is 587.6 nm. It's important to note that the lens does not come with any coating, as indicated in the item data.
