LC5749 12.7 mm Dia. CaF2 Plano-Concave Lens; EFL=-25mm Uncoated
The LC5749 is a Plano-Concave Spherical Lens with a diameter of 12.7 mm and a center thickness of 2.5 mm. This lens is sourced from Thorlabs and is uncoated. The effective focal length (EFL) of this lens is -25mm, making it a negative or diverging lens. The inner radius of the lens is 0, while the outer radius is also 0, indicating a plano surface.
The lens is made of Calcium Fluoride (CaF2) with the material ID mal-1963. It is designed to operate at a wavelength of 588 nm. The lens's shape is spherical, a common choice for its optical properties and ease of manufacturing. The uncoated feature of this lens means it does not have any additional layers to alter its optical properties, making it suitable for applications where specific coatings are not required.
