This is a 48-254 Double-Convex Lens, a high-quality optical component sourced from Edmund Optics. The lens boasts a 30mm diameter and a focal length of 75mm, making it suitable for a wide range of applications.
The lens is made from n-BK7 Schott, a popular optical glass due to its excellent transparency and low dispersion. This material ensures high-quality imaging and minimal chromatic aberration.
The lens features a double-convex geometry, meaning it has two spherical surfaces that curve outwards. This design provides a large field of view and low spherical aberration, making it ideal for imaging applications.
The lens is coated with the EDM VIS-0 std curve on both the front and back surfaces. This coating enhances its transmission in the visible spectrum, specifically between 425-675nm. It also provides protection against environmental factors, ensuring the lens maintains its performance over time.
The lens has a center thickness of 4.96mm and an edge thickness of 2mm. The inner and outer radii are not specified, indicating that they are not critical for the lens's performance in its intended application.
