LC2265 12.7 mm Dia. N-SF11 Plano-Concave Lens; EFL=-15mm Uncoated
The LC2265 is a Plano-Concave Spherical Lens with a 12.7 mm diameter, sourced from Thorlabs. This lens is designed for use in the optical spectrum with a wavelength of 587.6 nm. The lens is made from N-SF11 Schott glass, a popular material for its high refractive index and low dispersion.
The lens features an effective focal length (EFL) of -15 mm, indicating its diverging nature. This makes it suitable for applications where beam expansion is required. The lens has a center thickness of 3 mm and a concave radius of curvature of -11.7 mm. The inner and outer radii are both zero, suggesting a simple, circular geometry.
Notably, the lens is uncoated. This means that it does not have any additional layers to enhance its optical properties, such as reducing reflection or increasing transmission. However, uncoated lenses can be advantageous in certain applications where specific coatings may interfere with the desired optical behavior.
The lens's information is valid and in stock, according to the vendor's website. This ensures that users can rely on its availability for their optical systems.
