PLCC-10.0-25.8-C 10 mm Dia. N-BK7 Laser Grade Plano-Concave Lens; EFL=-50mm Uncoated
This is a PLCC-10.0-25.8-C laser grade plano-concave lens, sourced from CVI Laser Optics. The lens has a diameter of 10 mm and a center thickness of 2 mm, making it a compact and efficient optical component. The effective focal length (EFL) of this lens is -50 mm, indicating that it is a negative or diverging lens, which spreads out light rays.
The lens is made of N-BK7, a high-quality glass material known for its excellent optical properties. This material is often used in laser applications due to its low auto-fluorescence and high damage threshold. The lens is uncoated, meaning it does not have any additional layers to enhance its optical properties. However, this does not affect its performance in many applications, and uncoated lenses can be beneficial in certain scenarios due to their lower cost and simpler manufacturing process.
The lens's geometry is spherical, with a radius of curvature of -25.8 mm for the concave surface. The inner and outer radii are both 0, indicating that the lens has a uniform thickness. This lens is designed for use at a wavelength of 588 nm, making it suitable for a wide range of applications in this spectral region.
