K9L Glass Optical Lens For optical instrumental and other Optics

Spherical lenses—also sometimes referred to as singlets—are optical lenses that feature a spherical surface with a radius of curvature that is consistent across the entire lens. They are constructed such that the light entering them diverges or converges, depending on the lens design. Concave spherical lenses have a negative focal length that causes incident light to diverge (creating a virtual image). In contrast, convex spherical lenses have a positive focal length that causes incident light to converge (creating real and virtual images). The real images formed are highly focused, while the virtual images formed are highly magnified.

The main advantages of using spherical lenses in optical systems are their simpler surface design and lower manufacturing cost. These benefits make them suitable for various imaging applications in a diverse set of markets. Plano-convex lenses are often used in light collimation and monochromatic illumination operations that require infinite or near-infinite conjugate imaging properties. Plano-concave lenses are suitable for optical applications requiring the projection of light, the expansion of the light beam, or the expansion of the system’s focal length.
