355151 3 mm Dia. D-ZLAF52LA Molded Glass Aspheric Lenses; EFL=2 mm; NA=0.5 Uncoated
The 355151 3 mm Dia. D-ZLAF52LA Molded Glass Aspheric Lens is a high-quality optical component sourced from Thorlabs. This lens, with a catalog number 355151, is designed for use in a variety of optical systems, particularly those operating at a wavelength of 780 nm.
The lens features a circular base shape and is made from D-ZLAF52LA CGDM, a specialized glass material known for its optical properties. The lens has an outer radius of 0 mm and an inner radius of 0 mm, with a diameter of 3 mm. The edge thickness of the lens is 1.403 mm, while the center thickness is 1.892 mm, providing a balanced optical path.
The lens's geometry is defined by its effective focal length (EFL) of 2 mm and numerical aperture (NA) of 0.5. The aspheric design of the lens, represented by the coefficients k1, k2, and the aspheric terms a2, a4, a6, a8, a10, a12, a14, a16, ensures minimal spherical aberration and distortion, providing superior image quality.
The lens is uncoated, offering a cost-effective solution for applications where coating is not required or preferred. However, for applications where high transmission or protection against environmental factors is necessary, coated versions of this lens are available.
