Spherical lenses are designed for beam expansion and beam focusing. For high transmission across the desired spectral range, precision lenses are commonly used due to its optical materials. In creating lens shapes with excellent surface quality and high surface precision, critical and careful parameters need to be considered. For a well-suited variety of wavelengths from ultraviolet (UV) to infrared (IR), high-quality anti-reflection coatings are applied on the material.
The Plano Concave Spherical Lenses are simple negative lenses with a wide range of applications. It is useful for system power reduction when combined other optics. By the process of beveling, common negative lenses and sharp edges are removed.
