PLCX202 25.4 mm Dia. x 30 mm FL; Uncoated; Plano-Convex Lens

The PLCX202 is a Plano-Convex lens, a type of spherical lens with a single curved surface and a flat surface. This lens, sourced from WTS Photonics, has a diameter of 25.4 mm and a center thickness of 8.57 mm, making it suitable for a wide range of optical applications. The lens's base shape is circular, and it has an effective focal length (EFL) of 30 mm, which is the distance from the lens's center to the principal focus.

The lens's curvature is defined by a radius of 15.56 mm (R1), and its back focal length (BFL) is 24.35 mm. The BFL is the distance from the lens's rear surface to its principal focus. The lens is made of n-BK7 Schott glass, a popular material for optical elements due to its excellent optical properties and availability.

The lens is uncoated, meaning it does not have any anti-reflective or other coatings. This can be advantageous in certain applications where the introduction of a coating might alter the lens's optical properties. However, it's important to note that uncoated lenses can suffer from reflective losses, which can be significant at certain angles and wavelengths.

The lens is designed to operate at a wavelength of 546.1 nm, which is in the green part of the visible spectrum. This makes it suitable for applications that use green light, such as certain types of fluorescence microscopy.
