LA1027 N-BK7 Plano-Convex Lens; Dia:1 in; f=35.0 mm Uncoated

The LA1027 N-BK7 Plano-Convex Lens is a high-quality optical component sourced from Thorlabs. This lens, with a diameter of 1 inch (25.4 mm), is designed for use in a variety of optical systems, particularly those operating at a wavelength of 587.6 nm.

The lens features a plano-convex geometry, meaning one side is flat (plano) and the other is curved (convex). This design allows for efficient light collection and focusing. The radius of curvature of the convex surface is 18 mm, and the lens has a focal length of 35 mm (bfl), making it suitable for applications requiring moderate magnification or beam shaping.

The lens is made from N-BK7, a type of borosilicate glass known for its excellent optical properties. This material has a refractive index of approximately 1.5168 at the specified wavelength, which contributes to the lens's high optical performance. The lens's edge thickness is 2 mm, while the center thickness is 7.2 mm, providing structural rigidity and resistance to optical distortion.

Notably, this lens is uncoated. While coatings can enhance the performance of optical components by reducing surface reflections or protecting against environmental factors, an uncoated lens can be advantageous in certain applications due to its lower cost and simpler construction.
