Si-px-25.4-200 25.4 mm Dia. Silicon Plano-Convex Lens; EFL=200mm Uncoated

This is a Si-px-25.4-200 25.4 mm Dia. Silicon Plano-Convex Lens, sourced from Alkor Technologies. The lens is uncoated and features a spherical shape, designed for use in optical systems that require a specific focal length.

The lens has a diameter of 25.4 mm and a thickness at the edge of 2 mm, which gradually increases to 2.2 mm at the center. This design allows for a longer effective focal length (EFL) of 200 mm, making it suitable for applications that require a longer focus distance.

The lens is made of silicon, specifically silicon sal vil 1957, which is a common material in optical applications due to its transparency in the infrared region of the spectrum. The lens is designed to work with a wavelength of 10600 nm, making it suitable for use in systems operating in this region of the spectrum.

The lens is a Plano-Convex type, meaning it has a flat surface on one side and a curved surface on the other. This design is often used to collimate or focus light in optical systems. The curvature of the lens is defined by a radius of 483.1 mm, which contributes to its long focal length.

The lens does not have any coating, which means it will not have any additional protection or enhancement for its optical properties. However, this also means that it can be easily integrated into existing optical systems without worrying about compatibility issues with different coating types.
