L-MPC055 4 mm Dia. Plano-Concave Lens; EFL=-22mm Uncoated

The L-MPC055 is a plano-concave lens with a diameter of 4 mm, making it a compact and versatile optical component. This lens is sourced from Ross Optical, a reputable vendor known for their high-quality micro-optics. The lens features a center thickness of 1.5 mm, providing a sturdy base for integration into various optical systems.

The effective focal length (EFL) of this lens is -22 mm, indicating that it is a diverging lens. This means that it spreads out light rays, making it suitable for applications such as beam expansion or collimation. The lens's concave shape, defined by a radius of curvature (R1) of -11.3696 mm, contributes to its diverging properties.

The L-MPC055 is made from N-BK7 Schott glass, a common material in optical applications due to its excellent optical properties and high Abbe number. This particular lens is uncoated, meaning it does not have any additional layers to enhance its optical performance or protect it from environmental factors. However, uncoated lenses can still provide satisfactory performance in many applications, especially where cost-effectiveness is a priority.

This lens is designed to work with light of wavelength 587.6 nm, a common value in visible light spectrum applications. It is spherical in shape, a common and straightforward geometry that ensures easy integration into various optical systems.
