LA4148-405 25.4 mm Dia. UVFS Plano-Convex Lens; EFL=50mm 405nm V-Coat
The LA4148-405 is a Plano-Convex Spherical Lens with a diameter of 25.4 mm, designed for use in optical systems operating at a wavelength of 405 nm. This lens is sourced from Thorlabs, a leading vendor in the field of optical components.
The lens features an effective focal length (EFL) of 50.2 mm, making it suitable for a wide range of applications that require moderate magnification. The lens has a thickness of 2.1 mm at the edge and 5.8 mm at the center, providing a robust and stable platform for optical systems.
The LA4148-405 is made from UVFS material with the Mal-1965 index, ensuring high transmittance and low absorption at the operating wavelength. The lens is coated with Thorlabs' V-AR-405 coating on both the front and back surfaces, which reduces reflection and increases transmission at the design wavelength.
The lens is circular in shape, with no inner or outer radius specified, indicating a uniform curvature across the entire surface. This design provides a large clear aperture, allowing for high light throughput and low vignetting in optical systems.
