This is a 38.1 mm diameter Germanium Plano-Convex lens, offered by Alkor Technologies. The lens is uncoated and has an effective focal length (EFL) of 100mm, making it suitable for a wide range of optical applications.
The lens geometry is characterized by a thickness of 2mm at the edge and 2.6mm at the center. The inner radius is 0, while the outer radius is also 0, indicating a plano-convex shape. The lens is made of Germanium burnett material, which is known for its excellent transmission properties in the infrared region, specifically at 10600nm.
The lens type is spherical, which means it has a curved surface that is symmetric around the center. This type of lens is commonly used in various optical systems due to its simple design and versatile applications.
Please note that the lens does not come with any coating. Coatings are often applied to lenses to enhance their performance by reducing reflections, increasing transmission, or providing other benefits. However, this lens is uncoated, which may affect its performance in certain applications.
