38-613 35.0mm Dia. x 70.0mm FL; YAG-BBAR Coated; Plano-Convex Lens YAG-BBAR 500-1100nm
The 38-613 is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens boasts a diameter of 35.0mm and a focal length of 70.0mm, making it suitable for a wide range of optical applications. The lens is made from n-BK7 Schott, a popular optical glass due to its excellent optical properties and versatility.
The lens features a YAG-BBAR coating on both the front and back surfaces. This coating, which stands for Yttrium Aluminum Garnet - Broad Band Anti-Reflection, is designed to reduce reflection and increase transmission across a broad spectrum, specifically from 500nm to 1100nm. This makes the lens ideal for use in applications that require high transmission and low reflection, such as laser systems, imaging systems, and optical metrology.
The geometry of the lens includes a thickness of 1.49mm at the edge and 6.0mm at the center. The inner and outer radii are both 0mm, and the lens has a BFL (Back Focal Length) of 66.04mm and an EFL (Effective Focal Length) of 70.0mm. The lens's base shape is circular, adding to its versatility in various optical systems.
