The LC4796 is a plano-concave lens with a diameter of 12.7 mm, sourced from the renowned optical component manufacturer, Thorlabs. This lens is designed for use in systems operating at a wavelength of 588 nm. The lens's concave shape, defined by a radius of curvature (R1) of -13.8 mm, contributes to its negative focal length (EFL) of -30 mm.
The lens is made from UVFS material, identified as MAL-1965 in Thorlabs' material database. This material is chosen for its specific optical properties, which make it suitable for various applications. The lens's geometry also includes a center thickness of 3 mm, and it is offered uncoated.
The lens's uncoated state means it does not have any additional layers to alter its optical properties. This can be beneficial in certain applications where the natural properties of the material are desired, or where cost or simplicity are considerations. However, it's important to note that uncoated lenses can be more susceptible to environmental factors such as dust and moisture, and may not perform as well in high-intensity light applications due to issues like lens flare.
