BICC-25.4/100.0UV 25.4 mm Dia. x -98 mm FL; Uncoated; Double-Concave Lens
This is a double-concave lens, also known as a biconcave lens, sourced from the renowned optical component vendor, Laser Components. The lens has a base shape of a circle and is designed for use with a wavelength of 248 nm. The lens is made from fused sil mal-1965, a material known for its excellent optical properties.
The lens has a diameter of 25.4 mm and a thickness at the edge of 4.1 mm. The thickness at the center is 2.5 mm. The effective focal length (EFL) of the lens is -98 mm, indicating that it is a diverging lens, causing parallel light rays to spread out after passing through it. The first radius of curvature (r1) is -100 mm, and the second radius of curvature (r2) is 100 mm.
The lens does not have any coating, which means it is uncoated. This may result in a decrease in transmission and an increase in reflection, especially at the edges of the spectrum. However, uncoated lenses are often preferred when cost is a significant factor, or when the lens will be used in a controlled environment where the decrease in transmission and increase in reflection will not significantly impact the performance.
The item data is valid and the lens is in stock, according to the weblink provided. For more detailed information, please refer to the datasheet on the vendor's website.
