This product is a Plano-Concave Spherical Lens, sourced from the reputable vendor Laser Components. The lens boasts a diameter of 25.4 mm and a center thickness of 2.3 mm, making it a compact yet robust optical component.
The lens is designed with a negative focal length (EFL) of -200mm, indicating its concave nature. This feature allows the lens to converge incoming light rays, making it suitable for applications that require light to be focused onto a specific point.
The lens is made from UVFS material, identified as "UVFS Mal- 1965" in the item data. This material is optimized for use in the ultraviolet spectrum, specifically at a wavelength of 248nm.
Notably, this lens is uncoated. While coatings can enhance the performance of lenses by reducing reflections, increasing transmission, or providing other benefits, an uncoated lens can be advantageous in certain applications. For instance, it can offer greater simplicity, lower cost, and a reduced risk of optical damage due to coating degradation.
