SLB-50B-300P 50.0 mm Dia. x 300.8 mm FL; Double-Convex Lens Uncoated

The SLB-50B-300P 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.

The lens has a diameter of 50.0 mm and a center thickness of 5.0 mm, ensuring a robust and durable construction. The edge thickness is 3.0 mm, providing additional strength and resistance to edge chipping. The effective focal length (EFL) of this lens is 300.8 mm, making it suitable for applications that require a long focal length.

The lens is made of n-BK7 Schott, a popular optical glass due to its excellent optical properties and high Abbe number. This material ensures high transmittance and low dispersion, making it ideal for applications that require high image quality and color correction.

The radius of curvature for the first surface (R1) is 311.4 mm, while for the second surface (R2) it is -311.4 mm. This design ensures a high degree of focusing power and a wide field of view. The back focal length (BFL) of this lens is 299.2 mm, which is crucial for determining the lens's position in an optical system.

Notably, this lens is uncoated, which means it does not have any anti-reflective coatings. While this may result in higher reflective losses, it also means that the lens is less susceptible to damage from environmental factors, making it suitable for harsh environments.

In conclusion, the SLB-50B-300P is a robust and high-performing double-convex lens, ideal for applications that require a long focal length and high image quality. Its uncoated design makes it suitable for harsh environments, while its high-quality n-BK7 Schott material ensures excellent optical performance.
