CRD Laser - Laser Optical Lenses

The F-theta Scan Lens can provide a small focused spot size within a large field of view and minimize distortion, thereby achieving high-speed operation in applications such as marking, engraving, welding, and PCB drilling.

Beam expanders are lens assemblies that can change the diameter and divergence of a laser beam. Use Galilean telescope (no internal focus) beam expanders to change the diameter of a high power CO2 laser beam for a variety of applications. These beam expanders are available in a variety of different input beam diameter and magnification combinations.

Excellent optical performance and economy can be achieved with ZnSe precision meniscus lenses. Meniscus lenses are the "best form" single optical element of ZnSe due to their high refractive index. They focus smaller spot sizes than plano-convex lenses but cost less than aspheric lenses because they are easier to manufacture.

Use these silicon mirrors, which combine excellent thermal stability and high reflectivity, to build cost-effective optical systems.

These silicon mirrors, which combine excellent thermal stability and high reflectivity, enable cost-effective, high-performance galvo scanning systems to be built.

These flat windows, made of imported ZnSe material, protect valuable scanning lenses and focusing optics in industrial laser systems from debris, backsplash and other workplace hazards. These windows can be integrated directly into scanning lenses or focusing assemblies, or used separately.

Made of imported ZnSe material, these optical components precisely introduce CO2 lasers into the optical path along with other infrared laser beams, thus simplifying the process of aligning infrared optical systems.
