37-433 30mm Dia. N-SF5 Precision Aspheric Lens; EFL=22.5mm; NA=0.66 Uncoated
This is the 37-433 model from Edmund Optics, a high-precision aspheric lens with a 30mm diameter and a numerical aperture of 0.66. The lens is made from N-SF5 Schott, a high-refractive index glass, and is uncoated.
The lens has an effective focal length (EFL) of 22.5mm, making it suitable for applications that require a short focal length. The aspheric design of the lens helps to reduce spherical aberration, improving the overall image quality.
The lens has a center thickness of 15mm and an edge thickness of 6.62mm. The inner and outer radii are not specified, indicating that the lens is a meniscus design. The lens has a high numerical aperture (NA) of 0.66, which allows for a wide angle of view and high light-gathering capability.
The lens is uncoated, which means it does not have any anti-reflective coatings. This can lead to increased reflection at the air-glass interfaces, but it also means that the lens is less susceptible to damage from environmental factors.
The lens is currently in stock and can be purchased directly from the Edmund Optics website.
