15-027 200 mm Dia. N-BK7 Precision Aspheric Lens; EFL=300mm; NA=0.33 Uncoated

This is the 15-027 model from Edmund Optics, a high-precision 200 mm diameter N-BK7 Aspheric Lens. The lens boasts an Numerical Aperture (NA) of 0.33 and an effective focal length (EFL) of 300mm, making it suitable for a wide range of applications that require high-resolution imaging and precise focusing.

The lens is made from N-BK7, a high-quality borosilicate glass known for its excellent optical properties, including low autofluorescence and high transmittance across a broad spectrum. This makes the lens ideal for use in applications such as laser systems, beam shaping, and high-power imaging.

The aspheric design of the lens provides superior optical performance over traditional spherical lenses. It corrects for spherical aberration, a common issue in optical systems that can lead to distorted images and reduced resolution. The lens also features a unique geometry, with a inner radius of 0, an outer radius of 0, a thickness at the edge of 7.82, and a thickness at the center of 41.6.

The lens is uncoated, offering a cost-effective solution for applications where coating is not required or desired. However, for applications where high transmission, low reflectance, or environmental protection is needed, coating options are available from the vendor.

The lens is currently in stock and can be purchased directly from the Edmund Optics website. With its high-quality materials, precision design, and versatile specifications, the 15-027 200 mm Dia. N-BK7 Precision Aspheric Lens is an excellent choice for any application that requires high-performance imaging.
