The 112-0209E is a Plano-Concave Lens with a diameter of 25.4 mm and a focal length of -50 mm, making it a negatively powered lens. This lens is sourced from EKSMA Optics, a reputable vendor in the optical components industry. The lens's geometry includes a thickness edge of 6 mm and a center thickness of 2.8 mm, providing a sleek and compact design.

The lens is made of BK7 Schott, a high-quality borosilicate glass known for its excellent optical properties, including a low refractive index and low dispersion. This material makes the lens suitable for various applications, such as imaging systems, beam shaping, and laser applications.

Notably, this lens is uncoated, meaning it does not have any anti-reflective or other surface coatings. While this may result in higher reflective losses, it also means the lens can be used in a broader range of wavelengths, as coatings often have specific spectral ranges.
