This is a PLCC-15.0-38.6-C 15 mm Dia. N-BK7 Laser Grade Plano-Concave Lens, designed for use in a variety of optical applications. The lens, sourced from CVI Laser Optics, is a spherical lens with a plano-concave base shape and a circular geometry.
The lens has a diameter of 15 mm and a center thickness of 2 mm. It features an effective focal length (EFL) of -75 mm, making it suitable for applications that require a concave lens. The inner and outer radii are both 0, indicating a uniform curvature across the lens.
The lens is made from N-BK7 Schott, a popular material in the optical industry due to its excellent optical properties. This laser grade lens is designed for use with a wavelength of 588 nm.
The lens does not come with any coating, as indicated by the empty 'coating' field in the item data. This may make it suitable for applications where coating is not required or desired.
The lens is currently in stock and available for purchase. More detailed information about the lens, including its full specifications, can be found in the linked PDF document.
