354350-C 4.7 mm Dia. D-ZK3 Molded Glass Aspheric Lenses; EFL=4.5 mm; NA=0.4 AR 1050-1700nm

The 354350-C is a high-quality aspheric lens, precision-molded from D-ZK3 glass, a unique material known for its excellent optical properties. This lens boasts a 4.7 mm diameter and features an effective focal length (EFL) of 4.5 mm, making it suitable for a wide range of applications. The lens has a numerical aperture (NA) of 0.4, which contributes to its impressive light-gathering capability.

The lens is coated with a broadband anti-reflection (AR) coating, specifically designed to reduce surface reflections across 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 354350-C's aspheric design helps to correct spherical aberration, a common issue in traditional spherical lenses. This design ensures that the lens delivers high-quality, distortion-free images, even at wide apertures.

This lens is available from Thorlabs, a leading vendor in the optical components industry. According to the vendor's website, the lens is currently in stock, ensuring quick delivery times for those who need it. The product's webpage also provides additional technical specifications and drawings, which can be useful for those looking to integrate this lens into their optical systems.
