LA1576 N-BK7 Plano-Convex Lens; Dia:9.0 mm; f=12.0 mm Uncoated

The LA1576 N-BK7 Plano-Convex Lens is a high-quality optical component sourced from Thorlabs, a leading vendor in the field of optical equipment. This lens, with a diameter of 9.0 mm, is designed to focus or collimate light beams in various optical systems.

The lens is spherical in shape, with a plano-convex design. This means that one side of the lens is flat (plano), while the other side is curved (convex). The curvature of the convex side is defined by a radius of 6.2 mm. This design allows for efficient light collection and focusing, making the LA1576 an ideal choice for a wide range of applications.

The lens has an effective focal length (EFL) of 12.0 mm, which is the distance from the lens to the point where it focuses or collimates the light beam. This EFL, combined with the lens's diameter, determines the lens's angular field of view and its magnification power.

The LA1576 is made from N-BK7 glass, a popular material for optical lenses due to its excellent optical properties. This glass, manufactured by Schott, has a refractive index that optimizes light transmission and focusing.

The lens is uncoated, meaning it does not have any anti-reflective or other coatings. While coatings can enhance the performance of optical components in certain applications, uncoated lenses like the LA1576 offer simplicity and versatility, making them suitable for a wide range of uses.

According to the vendor's website, the LA1576 is currently in stock, ensuring quick delivery for your optical system needs. For more information, you can visit the product page at https://www.thorlabs.com/thorproduct.cfm?partnumber=LA1576.
