354560 6.325 mm Dia. D-ZK3 Molded Glass Aspheric Lenses; EFL=13.9 mm; NA=0.18 Uncoated

The 354560 6.325 mm Dia. D-ZK3 Molded Glass Aspheric Lens is a high-quality optical component sourced from Thorlabs. This lens, with a catalog number 354560, is designed for use in a variety of optical systems, particularly where high precision and performance are required.

The lens is made of D-ZK3 glass, a material known for its excellent optical properties. It has a diameter of 6.325 mm and a thickness at the edge of 2.282 mm. The effective focal length (EFL) of this lens is 13.9 mm, which is a crucial parameter in determining the lens's magnification power. The numerical aperture (NA) is 0.18, indicating the lens's light-gathering capability and its ability to resolve fine details.

The lens features an aspheric design, which is a type of lens surface that deviates from a simple spherical shape. This design helps to reduce spherical aberration, a common optical problem that can degrade image quality. The lens's front and back surfaces have been shaped with specific radii (r1 and r2) and thicknesses (thickness center and thickness edge) to achieve this aspheric profile.

The lens is uncoated, meaning it does not have any additional layers to enhance its optical properties. However, this does not affect its performance in many applications. The lens's geometry includes higher-order aspheric coefficients (a2 to a16), which contribute to its high precision and accuracy.
