355440 4.7 mm Dia. D-ZLAF52LA Molded Glass Aspheric Lenses; EFL=2.8 mm; NA=S1:0.26; S2:0.52 Uncoated
The 355440 4.7 mm Dia. D-ZLAF52LA Molded Glass Aspheric Lenses are precision optical components designed for a wide range of applications. Sourced from Thorlabs, these lenses are molded from D-ZLAF52LA glass, a unique material known for its excellent optical properties.
The lenses boast a diameter of 4.7 mm and an effective focal length (EFL) of 2.8 mm, making them suitable for use in systems with limited space. The aspheric design of these lenses helps to minimize spherical aberration, a common issue in optical systems, thereby improving image quality and resolution.
The lenses are uncoated, offering users the flexibility to apply their own coatings based on their specific requirements. The base shape is circular, and the lens features a thickness of 2.68 mm at the edge and 3.827 mm at the center.
The item data also provides detailed information about the lens's geometry, including the inner and outer radii, as well as the coefficients for the front and back surfaces. This level of detail allows users to precisely model the lens's behavior in their optical systems.
