355110-C 7.2 mm Dia. D-ZLAF52LA Molded Glass Aspheric Lenses; EFL=6.2 mm; NA=0.4 AR 1050-1700nm

The 355110-C is a high-quality aspheric lens offered by Thorlabs, designed for use in a variety of optical applications. This lens boasts a diameter of 7.2 mm and an effective focal length of 6.2 mm, making it a compact yet powerful option for your optical system.

The lens is made from D-ZLAF52LA, a molded glass material with a refractive index that supports a wide range of wavelengths, from 1050 nm to 1700 nm. This broad spectral range makes it a versatile choice for many applications, including those in the near-infrared spectrum.

The aspheric design of this lens helps to minimize spherical aberration, a common issue in traditional spherical lenses. This results in improved image quality and increased light gathering capability, which can be particularly beneficial in systems where high resolution and sensitivity are required.

The lens features an anti-reflective coating on both the front and back surfaces, further enhancing its performance. This coating, designated as THo C Bbar, reduces unwanted reflections and increases transmission, ensuring that more light reaches your target.

In terms of durability, the lens's edge thickness of 4.251 mm and center thickness of 5.158 mm provide robustness and resistance to damage. The lens's shape is aspheric, which not only aids in reducing spherical aberration but also provides a sleek and compact design.
