69-857 10 mm Dia. L-BAL35 Precision Aspheric Lens; EFL=10mm; NA=0.5 BBAR 425-675nm

The 69-857 is a high-precision aspheric lens, designed and manufactured by Edmund Optics. This lens is characterized by its 10 mm diameter and a numerical aperture (NA) of 0.5, making it suitable for a wide range of optical applications. The lens is made from L-BAL35, a material from Ohara, which is known for its excellent optical properties.

The lens is designed to work with a wavelength of 587.6 nm, and it features a focal length (EFL) of 10 mm. The aspheric design of the lens helps to reduce spherical aberration, thereby improving the overall image quality. The lens has a base shape of circular, which adds to its versatility in various optical systems.

The 69-857 lens comes with a broadband anti-reflection (BBAR) coating, specifically designed for the wavelength range of 425-675 nm. This coating helps to minimize surface reflections, thereby enhancing the transmission of light through the lens. The lens has a thickness of 1.69 mm at the edge and 4 mm at the center.

The front and back surfaces of the lens are coated with the same BBAR coating, ensuring high-transmission performance from both sides. The lens is currently in stock and available for immediate shipping. For more information, please refer to the provided weblink.
