PLCV309 38 mm Dia. x -500 mm FL; Uncoated; Plano-Concave Lens

The PLCV309 is a plano-concave lens with a diameter of 38 mm and a focal length of -500 mm, making it a negatively powered lens. This lens is sourced from WTS Photonics, a reputable vendor in the optical industry. The lens's geometry includes a thickness edge of 2.7 mm and a thickness center of 2 mm, providing a slim profile that minimizes optical aberrations.

The lens is made of n-BK7 Schott glass, a popular material in optical systems due to its high transparency and excellent optical properties. The base shape is circular, ensuring uniform light distribution and reducing vignetting effects. The lens is uncoated, which means it does not have any anti-reflective or protective coatings. This may result in higher reflective losses and potential surface damage, but it also allows for greater customization and compatibility with various coating types.

The PLCV309 is designed for use at a wavelength of 546.1 nm, making it suitable for applications such as monochromatic imaging and spectroscopy. Its spherical shape ensures consistent optical performance across the lens's surface, while the concave design allows for effective light collimation and divergence control.
