LM11-25-100 25.4 mm Dia. N-BK7 Negative Meniscus Lens; EFL=-100mm Uncoated
The LM11-25-100 is a spherical lens with a base shape of a circle, sourced from CeNing Optics. This lens is a negative meniscus type, characterized by its concave-convex geometry. The lens has a diameter of 25.4 mm and a thickness at the edge of 4.5 mm, while the center thickness measures 3 mm.
The effective focal length (EFL) of this lens is -100 mm, indicating that it is a diverging lens, which spreads out light rays. The first radius of curvature (r1) is 90 mm, and the second radius (r2) is 32.59 mm. The back focal length (bfl) is -99.2 mm. The lens does not have an inner or outer radius, suggesting a uniform curvature.
The lens is made of n-BK7 Schott, a popular optical glass due to its excellent optical properties and wide transparency range. The lens is designed for a wavelength of 546.1 nm. It does not come with any coating, which may affect its light transmission and scattering properties.
