The SLB-50B-50P is a high-quality double-convex lens offered by OptoSigma, a renowned vendor in the optical industry. This lens, with a base shape of a circle, is designed for use in a wide range of optical applications, thanks to its precise geometry and material composition.
The lens has a diameter of 50.0 mm and a focal length of 52.7 mm, making it a versatile choice for many setups. The edge thickness is 3.0 mm, while the center thickness is 15.8 mm, providing a robust structure that can withstand typical use. The effective focal length (EFL) is 52.7 mm, and the back focal length (BFL) is 47.3 mm, which are crucial specifications for accurate optical modeling and design.
The lens is made of n-BK7 Schott, a popular optical glass known for its excellent optical properties. This material ensures high transmittance and low dispersion, making it suitable for various applications, including imaging, beam shaping, and laser systems.
Notably, this lens is uncoated, which means it does not have any additional layers to enhance its optical properties. While coatings can improve characteristics such as transmission and reflection, an uncoated lens can be advantageous in certain situations, such as when cost, simplicity, or specific spectral requirements are considerations.
