354453-C 6 mm Dia. D-ZK3 Molded Glass Aspheric Lenses; EFL=4.6 mm; NA=0.5 AR 1050-1700nm

The 354453-C is a high-quality aspheric lens, precision-molded from D-ZK3 glass, a type of glass known for its excellent optical properties. This lens boasts a diameter of 6 mm and an effective focal length (EFL) of 4.6 mm, making it suitable for a wide range of optical applications. The lens has a high numerical aperture (NA) of 0.5, which allows for a larger light-gathering capacity and improved resolution.

The lens is coated with a broadband anti-reflective (AR) coating, specifically designed to reduce surface reflections in the 1050-1700nm wavelength range. This coating enhances the lens's performance in infrared (IR) applications, ensuring minimal loss of light due to reflection.

The lens's geometry is defined by its inner and outer radii, both of which are 0 in this case. The lens has a thickness of 1.743 mm at the edge and 3.135 mm at the center. The aspheric design of the lens helps to correct spherical aberration, a common issue in optical systems, thereby improving the overall image quality.

The lens's shape is defined by its conic constant (k1) and aspheric coefficients (a2 to a16). In this case, k1 is 0, and the aspheric coefficients for both the front and back surfaces of the lens are provided, allowing for a high degree of customization and fine-tuning of the lens's optical properties.
