The 89-148 is a high-quality double-convex lens, boasting a 10mm diameter and a focal length of 50mm. This lens is sourced from the reputable vendor, Edmund Optics, and is available in stock for immediate use. The lens is constructed from the renowned material, n-BK7 Schott, which is known for its excellent optical properties and versatility.
The lens features a double-convex geometry, characterized by its base shape of a circle and a shape defined as spherical. The inner radius of the lens is zero, while the outer radius is also zero, indicating a symmetrical design. The lens has a thickness of 2.01mm at the edge and 2.5mm at the center, providing a robust structure.
The 89-148 lens is coated with EDM VIS-EXT on both the front and back surfaces. This coating enhances the lens's performance in the visible light spectrum, specifically within the wavelength range of 350-700nm. The coating ensures optimal light transmission, reducing losses and improving the overall efficiency of the optical system.
