355230-1064 6.325 mm Dia. D-ZLAF52LA Molded Glass Aspheric Lenses; EFL=4.5 mm; NA=0.55 1064nm V-Coat

The 355230-1064 is a high-quality aspheric lens, precision-molded from D-ZLAF52LA glass, a unique material with a high refractive index and excellent transmission properties in the near-infrared region. This lens is designed for use at a wavelength of 780 nm and features a diameter of 6.325 mm and a thickness of 1.688 mm at the edge, making it suitable for a wide range of optical applications.

The lens boasts an effective focal length (EFL) of 4.5 mm, providing a compact and efficient optical solution. The aspheric design (R1: 0, R2: -3.576018) ensures high optical performance, reducing spherical aberration and delivering sharp, clear images. The lens has a high numerical aperture (NA) of 0.55, allowing for a wide angle of view and high light-gathering capability.

The lens is coated with a broadband anti-reflective coating, specifically designed for 1064 nm, ensuring high transmission and low reflectance. This coating, denoted as 'tho v-ar-1064', is applied to both the front and back surfaces of the lens, further enhancing its performance and durability.
