L-MPC060 4 mm Dia. Plano-Concave Lens; EFL=-29mm Uncoated

The L-MPC060 is a plano-concave lens with a diameter of 4 mm, sourced from the renowned optical components manufacturer, Ross Optical. This lens is designed with a center thickness of 1.5 mm and a focal length of -29 mm, making it suitable for applications that require a negative focal length.

The lens's base shape is circular, and its geometry is spherical, which is a common feature in optical lenses due to its ease of manufacturing and high optical quality. The inner and outer radii of the lens are 0, indicating a plano surface on both sides. 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 uncoated, which means it does not have any anti-reflective or other coatings. While coatings can enhance the performance of a lens by reducing reflections, increasing transmission, or providing other benefits, an uncoated lens can be a cost-effective solution for applications where such enhancements are not necessary.

This lens is designed to work at a wavelength of 587.6 nm, which is in the visible light spectrum. It is important to note that the performance of the lens can vary depending on the wavelength of the light it is intended to focus or transmit.
