Si-px-76.2-200 76.2 mm Dia. Silicon Plano-Convex Lens; EFL=200mm Uncoated
The Si-px-76.2-200 is a 76.2 mm diameter Plano-Convex lens made of Silicon, sourced from Alkor Technologies. This lens is designed for use in the infrared spectrum, specifically at a wavelength of 10600 nm. The lens features an effective focal length (EFL) of 200mm, making it suitable for applications that require a longer focal length.
The lens geometry includes a thickness of 3mm at the edge and 4.5mm at the center. The lens's base shape is circular, and it has a spherical shape with a radius of curvature (R1) of 483.1. The lens does not have an inner radius (R2), and the outer radius (R3) is also not specified, indicating that the lens is a simple Plano-Convex design.
The lens is made of silicon, identified as "silicon sal vil 1957" in the Material ID field. This specific type of silicon is commonly used in optical applications due to its excellent transmission properties in the infrared spectrum.
Notably, this lens is uncoated. Coatings are often applied to lenses to enhance their performance by reducing reflections, increasing transmission, or providing other benefits. However, this lens is designed to operate without a coating, which may be suitable for certain applications.
The vendor, Alkor Technologies, indicates that this item is in stock on their website, providing users with the assurance that they can readily acquire this lens for their optical systems.
