This product is a Plano-Concave Spherical Lens, offered by CVI Laser Optics with the catalog number PLCC-25.4-51.5-C. 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 25.4 mm and a center thickness of 2.6 mm. The effective focal length (EFL) of this lens is -100mm, making it a concave lens. The inner radius of the lens is 0 mm, and the outer radius is also 0 mm, indicating a plano surface on one side and a concave surface on the other.
The lens is made from N-BK7 glass, a popular 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.
The lens is designed to operate at a wavelength of 588 nm. It is important to note that the performance of the lens can vary depending on the specific wavelength and angle of incidence of the light it is used with.
