114-0128E 12.7 mm Dia. x -200 mm FL; Uncoated; Double-Concave Lens

The 114-0128E is a double-concave lens with a diameter of 12.7 mm and a focal length of -200 mm, sourced from EKSMA Optics. This lens is a spherical type, featuring a base shape of a circle and a Sub Type of Spherical Lens (Concave-Concave).

The lens's geometry is meticulously designed, with an edge thickness of 2 mm and a center thickness of 1.8 mm. The inner and outer radii are 0, and the radii of curvature are -207.8 mm and 207.8 mm for the first and second surfaces, respectively.

The lens is made of n-BK7 Schott material, a popular choice for its high refractive index and low dispersion. It is designed to operate at a wavelength of 546 nm. The lens does not come with any coating, offering a bare, uncoated surface.

This lens is a versatile component, suitable for various applications that require a negative focal length and a small diameter. It is currently in stock and available for immediate purchase, as indicated by its weblink status.
