This is a Si-px-38.1-100 38.1 mm Dia. Silicon Plano-Convex Lens, a high-quality optical component sourced from Alkor Technologies. The lens is designed with a spherical shape and a base shape of a circle, making it suitable for a wide range of optical applications.
The lens has a diameter of 38.1 mm and a thickness at the edge of 2 mm. The thickness at the center is 2.8 mm, providing a robust structure that can withstand typical handling and usage. The effective focal length (EFL) of this lens is 100 mm, making it a medium to long-range focal length lens.
The lens is made of silicon, specifically silicon sal vil 1957, which is known for its excellent optical properties. The material is uncoated, which means it does not have any additional layers to enhance or modify its optical characteristics. This could be beneficial in applications where the natural properties of silicon are desired.
The lens is designed to work with a wavelength of 10600 nm, making it suitable for infrared (IR) applications. The inner and outer radii are both zero, indicating a simple plano-convex design.
