The L-PCC041 is a plano-concave lens with a diameter of 18 mm, sourced from the renowned optical component vendor, Ross Optical. This lens is designed with a center thickness of 1.5 mm and a negative effective focal length (EFL) of -350 mm, making it suitable for applications that require light convergence or divergence.
The lens is spherical in shape, with a radius of curvature (R1) of -180.88 mm for the concave surface. The inner and outer radii are 0, indicating that the lens has a uniform curvature throughout. The lens is made of N-BK7 Schott, a popular optical glass known for its excellent optical properties and versatility.
The lens is uncoated, which means it does not have any anti-reflective or other surface coatings. While this may result in higher reflective losses, it also means that the lens is less susceptible to damage from environmental factors or handling.
This lens is designed to work with light of wavelength 587.6 nm, which is within the visible spectrum. It is in stock and available for immediate purchase, as indicated by its valid weblink status.
