L-MPC065 4 mm Dia. Plano-Concave Lens; EFL=-45.5mm Uncoated

The L-MPC065 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 -45.5 mm, indicating its diverging nature. This makes it suitable for applications that require beam expansion or divergence, such as in laser systems or imaging applications. The lens's concave shape is defined by a radius of curvature (R1) of -23.5144 mm, contributing to its diverging properties.

The lens is made from N-BK7 Schott glass, a common and reliable material in the optical industry. This material is known for its excellent optical properties, including high transparency and low dispersion, making it suitable for a wide range of applications.

The lens is uncoated, meaning it does not have any additional layers to enhance its optical properties. While this may limit its use in certain high-precision applications, it can be advantageous in applications where cost-effectiveness and simplicity are prioritized.

This lens operates at a wavelength of 587.6 nm, which is within the visible light spectrum. This makes it suitable for applications involving visible light, such as in optical communication, imaging, or display technologies.
