LA1541 N-BK7 Plano-Convex Lens; Dia:30.0 mm; f=200.0 mm Uncoated

The LA1541 N-BK7 Plano-Convex Lens is a high-quality optical component sourced from Thorlabs, a leading vendor in the field of optical components. This lens, with a diameter of 30.0 mm, is designed for use in a variety of optical systems, offering a focal length of 200.0 mm, making it suitable for applications that require a longer focal length.

The lens is made of N-BK7, a type of borosilicate glass known for its excellent optical properties. This material is often used in high-precision optical systems due to its low coefficient of thermal expansion and high homogeneity. The lens is uncoated, which means it does not have any additional layers to enhance its optical properties. However, uncoated lenses can be advantageous in certain applications where low reflectivity is desired.

The geometry of the lens is spherical, with a planar surface on one side and a convex surface on the other. The planar surface has a thickness of 1.7 mm at the edge and 2.8 mm at the center, while the curved surface has a radius of curvature of 103 mm. The back focal length of the lens is 197.5 mm, and it has no inner or outer radius, indicating a uniform thickness.

This lens is designed to work at a wavelength of 587.6 nm, making it suitable for applications that use yellow light, such as certain types of lasers or light-emitting diodes (LEDs). The lens is part of Thorlabs' extensive catalog of optical components, and it is currently in stock, ensuring quick and reliable delivery.
