Si-px-50.8-200 50.8 mm Dia. Silicon Plano-Convex Lens; EFL=200mm Uncoated

This is a Si-px-50.8-200 50.8 mm Dia. Silicon Plano-Convex Lens, a high-quality optical component sourced from Alkor Technologies. The lens, with a diameter of 50.8 mm, is designed for use in a variety of optical systems, offering a focal length of 200mm.

The lens is spherical in shape, specifically a Plano-Convex design, which means it has a flat surface on one side and a curved surface on the other. This design is often used to focus light onto a single point, making it ideal for applications such as imaging and laser systems. The lens's geometry includes a thickness of 2.5mm at the edge and 3.2mm at the center, providing a robust structure while maintaining a low profile.

The lens is made from silicon, specifically silicon sal vil 1957, a material known for its excellent optical properties. It is uncoated, meaning it does not have any additional layers to enhance its optical performance. However, this does not detract from its quality, as silicon inherently has low absorption and scattering coefficients, making it a suitable choice for many applications.

The lens is designed to work with a wavelength of 10600 nm, making it suitable for use in infrared (IR) systems. It is important to note that the lens does not have any coating, which may affect its performance in certain applications. Therefore, users should consider this factor when selecting this lens for their specific needs.
