lens
Focus lens to focus on laser beams, used for material handling processing.
Wave energy company production flat convex, convex lenses, but also often double convex custom-made according to customer requirements and minus focal length lens and CO2 laser cutting machine lens repair service. We internal optical engineer has the design components or optical system ability, can accurately provide you need performance. Please contact our sales and engineering personnel connection to get products quotation.
Used for CO2 laser system flat to a burning
Flat convex suitable for laser heat treatment, welding, cutting and infrared radiation collection, in these applications, flare size or the image quality is not the most important factor. By diffraction limit in the specular circle of optical system, values the shape of the lens to system performance and no substantial effect, ping convex became an economic choice.
In order to obtain satisfactory performance, ping convex curved toward the alignment should incident beam, or toward the distance and conjugate distance (things like distance is known collectively as conjugate distance) longer that end.
