15-009 100 mm Dia. N-BK7 Precision Aspheric Lens; EFL=150mm; NA=0.33 Uncoated
This is the 15-009 model from Edmund Optics, a 100 mm diameter N-BK7 precision aspheric lens with a numerical aperture of 0.33 and no coating. The lens is designed for use at a wavelength of 587.6 nm.
The lens's geometry is defined by an inner radius of 0, an outer radius of 0, a diameter of 100 mm, and a thickness at the edge of 5.11 mm. The effective focal length (EFL) is 150 mm, and the radius of curvature (R1) is 77.52 mm. The back focal length (BFL) is 135.5 mm, and the thickness at the center is 22 mm. The conic constant (K1) is -0.715.
The lens's numerical aperture (NA) is 0.33, and it has a clear aperture with no front or back threads. The front and back dimensions are 0, with the front and back refractive indices being 1 and the Abbe number being 64.17.
The lens is uncoated, meaning it does not have any additional layers to enhance its optical properties. This can be beneficial in certain applications where the user wants to control the coating or where cost is a factor.
The lens is currently in stock and can be purchased directly from the Edmund Optics website using the provided weblink.
