L-MPC025 4 mm Dia. Plano-Concave Lens; EFL=-8mm Uncoated

The L-MPC025 is a plano-concave lens with a diameter of 4 mm, sourced from Ross Optical. This lens is designed for use in micro-optics applications and features a center thickness of 0.8 mm and an effective focal length (EFL) of -8 mm. The plano-concave shape, characterized by two spherical surfaces with one side being flat and the other side curved inward, is ideal for dispersing or converging light.

The lens is made from n-BK7 Schott, a high-quality borosilicate glass known for its excellent optical properties, including a high Abbe number and low dispersion. This makes the L-MPC025 suitable for applications that require precise optical performance, such as imaging systems, beam shaping, and laser applications.

The lens is uncoated, meaning it does not have any additional layers to enhance its optical properties or protect it from environmental factors. However, uncoated lenses can offer superior light transmission and are often more cost-effective.

Please note that the lens is designed for a wavelength of 587.6 nm. This means it is optimized for use with light sources of this wavelength, although it can still be used with other wavelengths, albeit with potentially different optical performance.
