38-397-INK 12.5mm Dia. x 12.5mm FL; NIR II; Inked; Plano-Convex Lens NIR II 750-1550nm

The 38-397-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 12.5mm, is designed for use in the near-infrared (NIR) spectrum, specifically between 750nm and 1550nm, as indicated by its NIR II coating.

The lens's geometry is characterized by its edge thickness of 1.22mm and center thickness of 2.7mm. It has an effective focal length (EFL) of 25mm, a front radius (R1) of 12.92mm, and a back focal length (BFL) of 32.22mm. The lens is made of N-BK7 Schott, a popular optical glass due to its excellent optical properties and availability.

The lens's coating is a standard curve for NIR II, applied to both the front and back surfaces. This coating enhances the lens's performance in the NIR spectrum by reducing surface reflections and increasing transmission. The lens's base shape is circular, and its shape is spherical, which is common in optical systems due to its simplicity and ease of manufacturing.

The lens's status is "Valid - in stock," according to the weblink provided, ensuring availability for immediate use. This lens is an excellent choice for applications that require high-quality performance in the NIR spectrum, such as biomedical imaging, spectroscopy, and night vision systems.
