47-729 25 mm Dia. L-BAL35 Precision Aspheric Lens; EFL=18.75mm; NA=0.66 Uncoated

The 47-729 is a high-precision aspheric lens offered by Edmund Optics, boasting a 25 mm diameter and a numerical aperture (NA) of 0.66. This lens is designed for use with a wavelength of 587.6 nm and is manufactured from L-BAL35 material, a product of Ohara.

The lens features an effective focal length (EFL) of 18.75 mm, making it suitable for a variety of applications that require high-resolution imaging or light collection. The aspheric design of the lens helps to minimize spherical aberration, a common issue in traditional spherical lenses, thereby improving the overall image quality.

The lens has a center thickness of 10 mm and an edge thickness of 1.63 mm, providing a robust structure while maintaining a relatively lightweight profile. The inner and outer radii of the lens are 0 mm, contributing to its aspheric shape.

The lens is uncoated, which means it does not have any additional layers to enhance its optical properties. While this may result in a slightly lower transmission rate compared to coated lenses, it can be advantageous in applications where minimal reflection is required.

The 47-729 lens is currently in stock and available for purchase through the Edmund Optics website. With its high-quality construction, precise design, and versatile specifications, this lens is an excellent choice for a wide range of optical applications.
