Plano-Concave Lenses
Plano-Concave Lenses
The plano concave lens is negative spherical lens, the lens is thinner in the middle and thicker at edges, and its surface is sunken inward, hence the name concave lens.
The concave lens has a divergent effect on light. When parallel light passes through the concave lens, the light diverges outward as if from a virtual focus, called a "virtual focus", located on the side of the incident light of the lens. The production process of concave lens includes grinding, polishing, edging and coating. After production, the concave lens needs to undergo strict quality testing, including radius, irregularity, surface quality, centration tolerance focal length and coating scans to meet the optical performance indicators required by customers.
CLZ Optical Co., Ltd. provides a variety Catalog of Plano Concave Lenses product. These stand plano concave can be widely used in optical beam shaping, beam expanders, laser cutting, projection systems and optical detection laser applications.
In addition to the Plano concave lens in the catalog, CLZ Optical provides customized lenses according to the customer's drawings or specifications. Materials include optical glass, fused silica, fluoride, silicon, etc. Optical lenses of different materials are suitable for different optical system applications. We recommend the use of a concave lens in combination with other optical components for complex optical systems, and its wide application field is reflected in the following aspects.
The application of plano concave lenses:
In microscopes and telescopes, plano concave lenses are used to correct the optical path and improve the quality of optical imaging.
In medical laser equipment and endoscopes, plano concave lenses are used for beam control and focusing to ensure the accuracy and safety of the equipment.
In fiber optic communication systems, flat concave lenses are used for coupling and separating optical signals to improve communication efficiency.
In the field of laser processing, flat concave lenses can be combined with conical lenses to form a circular Bessel beam, achieving multiple circular hole processing of products.
