G312403000 31.5 mm Dia. N-BK7 Plano-Convex Lens; EFL=80mm Uncoated

The G312403000 is a 31.5 mm diameter Plano-Convex lens, sourced from Qioptiq Photonics, a leading vendor in the field of precision optics. This lens is designed for use in a wide range of optical systems, offering a focal length of 80mm and a high-quality N-BK7 glass substrate.

The lens features a spherical geometry, with a planar face on one side and a convex face on the other. The convex face has a radius of curvature of 41.57 mm, providing a well-defined focal point and minimal spherical aberration. The lens has a thickness of 1.9 mm at the edge and 5 mm at the center, offering a robust and stable platform for optical systems.

The N-BK7 glass substrate is a borosilicate crown glass, known for its excellent optical properties and high damage threshold. It has a refractive index of approximately 1.5168 at the specified wavelength of 588 nm, making it suitable for use in a wide range of applications.

Notably, this lens is uncoated, meaning it does not have any anti-reflective or protective coatings. While this can make the lens more susceptible to environmental damage and scattering, it also allows for greater customization, as users can apply coatings that best suit their specific application.
