15-006 100 mm Dia. N-BK7 Precision Aspheric Lens; EFL=100mm; NA=0.5 Uncoated

This is the 15-006 model from Edmund Optics, a 100 mm diameter N-BK7 precision aspheric lens with a numerical aperture (NA) of 0.5 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 mm, an outer radius of 0 mm, a diameter of 100 mm, and a thickness at the edge of 5.9 mm. The effective focal length (EFL) is 100 mm, and the radius of curvature (R1) is 51.68 mm. The back focal length (BFL) is 78.18 mm, and the thickness at the center is 33.1 mm. The lens's conic constant (K1) is -1.

The lens's NA, a measure of its ability to gather light and resolve fine detail, is 0.5. The front surface has a decentering of 4.05e-07 mm, a slope of 2.66e-11 radians, a curvature of 1.48e-15 mm, and a conic constant of 1.33e-19. The aspheric deformation is -2.04e-23 mm.

This lens is uncoated, meaning it does not have any additional layers to protect it or enhance its optical properties. This may make it more susceptible to damage and less efficient at transmitting light, but it can also make it more cost-effective and suitable for certain applications.
