The 33-390 is a Double-Convex Lens, a type of Spherical Lens, sourced from Edmund Optics. With a diameter of 12mm and a focal length of 24mm, it boasts an impressive effective focal length (EFL) of 24mm. The lens's geometry is characterized by its edge thickness of 2.48mm and center thickness of 4mm, making it a robust and reliable choice for various applications.
The lens is made from n-BK7 Schott, a high-quality optical glass known for its excellent transparency and low dispersion. This makes the lens suitable for use across a wide spectrum, specifically designed for the visible light range of 425-675nm.
The 33-390 features a standard VIS 0deg coating on both the front and back surfaces. This coating enhances the lens's performance by reducing surface reflections, thereby increasing transmission and improving overall image quality.
The lens's inner and outer radii are 0mm, indicating a uniform curvature throughout. The front and back radii of curvature are 24.108mm and -24.108mm, respectively, suggesting a symmetrical design that minimizes spherical aberration.
