22-717 100mm Dia. N-BK7 Precision Aspheric Lens; EFL=150mm; NA=0.33 BBAR 600-1050nm

This is a high-quality 100mm diameter aspheric lens, offered by the renowned optical vendor, Edmund Optics. The lens, cataloged under the number 22-717, is designed for use in the near-infrared spectrum, with a central wavelength of 587.6nm.

The lens boasts a numerical aperture (NA) of 0.33, which is a measure of its light-gathering ability. A higher NA allows for greater resolution and light collection, making this lens suitable for applications that require high precision and resolution.

The lens is made from N-BK7, a type of high-quality borosilicate glass, which is known for its excellent optical properties and durability. The aspheric design of the lens helps to reduce spherical aberration, a common optical issue that can degrade image quality.

The lens features a focal length (EFL) of 150mm, which is the distance from the lens to the point where it focuses light. This makes it suitable for use in imaging systems where a longer focal length is required.

The lens is coated with BBAR 600-1050, a type of anti-reflection coating that reduces unwanted reflections and increases transmission in the 600-1050nm range. This coating helps to improve the overall efficiency and contrast of the lens.

The lens has a thickness of 5.11mm at the edge and 22mm 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.
