354280-1064 6.5 mm Dia. D-ZK3 Molded Glass Aspheric Lenses; EFL=18.4 mm; NA=0.15 1064nm V-Coat
The 354280-1064 is a high-quality aspheric lens, manufactured by Thorlabs, designed for use with a wavelength of 780nm. This lens is made from D-ZK3 CGDM glass, a material known for its excellent optical properties. The lens has a diameter of 6.5mm and a thickness of 1.775mm at the edge, with a center thickness of 2.178mm. The effective focal length (EFL) of this lens is 18.4mm, making it suitable for a variety of optical applications.
The lens features an aspheric surface with a radius of curvature (R1) of 0mm and a conic constant (K1) of 0. The back surface of the lens has a radius of curvature (R2) of -10.667684mm and a conic constant (K2) of -0.686129. The lens has a numerical aperture (NA) of 0.15, which is a measure of the lens' light-gathering ability.
The 354280-1064 comes with a V-coat coating on both the front and back surfaces. This coating, specifically designed for 1064nm, reduces reflection and increases transmission, enhancing the overall performance of the lens. According to the vendor's website, this item is currently in stock, making it readily available for immediate use.
