PLCV401 40 mm Dia. x -50 mm FL; Uncoated; Plano-Concave Lens

The PLCV401 is a plano-concave lens with a diameter of 40 mm and a focal length of -50 mm, sourced from WTS Photonics. This lens is designed for use in optical systems where a negative focal length is required. The plano-concave shape, characterized by a flat surface and a concave surface, allows for precise control of light paths.

The lens is made from n-BK7 Schott glass, a popular material in optical applications due to its high transparency and excellent optical properties. The geometry of the lens includes an edge thickness of 11.42 mm and a center thickness of 2 mm, providing structural integrity while minimizing unwanted optical effects.

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 applications, it can be advantageous in others where specific coatings may interfere with the desired optical performance.

The PLCV401 is designed for use at a wavelength of 546.1 nm, making it suitable for a wide range of applications in the visible light spectrum. Its spherical shape ensures consistent optical performance across the entire surface of the lens.
