PLCV201 25.4 mm Dia. x -35 mm FL; Uncoated; Plano-Concave Lens

The PLCV201 is a plano-concave lens with a diameter of 25.4 mm and a focal length of -35 mm, making it a negatively powered lens. This lens is sourced from WTS Photonics, a reputable vendor in the optical industry. The lens is uncoated, which means it does not have any additional layers to protect it from environmental factors or to enhance its optical properties.

The lens's geometry is characterized by its edge thickness of 7.18 mm and center thickness of 2 mm. The inner and outer radii are both 0, indicating a plano surface on one side and a concave surface on the other. The back focal length (BFL) is -36.32 mm, which is slightly longer than the effective focal length (EFL) due to the lens's concave shape.

The lens is made of n-BK7 Schott glass, a common material in optical applications due to its excellent optical properties and high Abbe number. The lens is designed to operate at a wavelength of 546.1 nm, which is in the green part of the visible spectrum.

This lens is suitable for a variety of applications, including beam shaping, collimation, and focusing. Its compact size and negative power make it a versatile component in optical systems. However, due to its uncoated nature, it may be more susceptible to damage from environmental factors and may have lower transmission compared to coated lenses.
