69-853 10 mm Dia. L-BAL35 Precision Aspheric Lens; EFL=10mm; NA=0.5 Uncoated

This is the 69-853 10 mm Dia. L-BAL35 Precision Aspheric Lens, a high-quality optical component sourced from Edmund Optics. The lens is characterized by its uncoated surface and a numerical aperture (NA) of 0.5, making it suitable for a wide range of optical applications.

The lens has an effective focal length (EFL) of 10mm, which is the distance from the lens's principal point to the focal point when the lens is focused at infinity. This makes it a medium focal length lens, ideal for applications that require a balance between magnification and field of view.

The lens is made from L-BAL35, a type of optical glass developed by Ohara. This material is known for its excellent optical properties, including high transparency and low dispersion, making it suitable for use in high-precision optical systems.

The lens has a base shape of circular, with an inner radius and outer radius of 0. The diameter of the lens is 10mm, and it has a thickness of 1.69mm at the edge and 4mm at the center. The aspheric design of the lens helps to reduce spherical aberration, improving the overall image quality.

The lens is uncoated, meaning it does not have any anti-reflective coatings. While this can lead to increased reflection at the air-glass interface, it also means that the lens is less susceptible to damage from environmental factors, making it a durable choice for many applications.
