The 69-861 is a high-precision aspheric lens offered by Edmund Optics, boasting a diameter of 10 mm and a numerical aperture (NA) of 0.5. This lens is designed for use in the near-infrared (NIR) spectrum, specifically at a wavelength of 587.6 nm.
The lens is crafted from L-BAL35, a material from Ohara, which is known for its excellent optical properties. The aspheric design of the lens helps to minimize spherical aberration, thereby improving the quality of the image formed.
The lens features a focal length (EFL) of 10 mm, which is the distance between the lens and the point where it focuses light. This makes it suitable for applications that require a compact optical system.
The lens is coated with BBAR 600-1050, a broadband anti-reflection coating that reduces reflection across the 600-1050 nm range. This coating enhances the transmission of light through the lens, thereby improving the efficiency and quality of the optical system.
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 600-1050 coating, ensuring high transmission and low reflection from both sides.
In terms of shape, the lens is circular, making it suitable for a wide range of applications. The lens is currently in stock and available for immediate shipping, as indicated by its valid weblink status.
