Viewing Systems

Product catalog summary

Overview: The document describes a Through the Lens Viewer designed for industrial laser beam delivery systems. It allows users to view the laser beam's path and focus through a television monitor, ensuring precise alignment and positioning on the workpiece.

Specifications: The viewer is compatible with ZnSe, BK7, or fused Silica lenses with focal lengths from 2.5 to 10 inches. It supports various laser wavelengths, including Excimers, Nd:YAG, and CO2. The clear aperture is 1.4 inches, and magnification ranges from 13.5X to 66X depending on the lens used. The viewer requires minimal mounting space and can be integrated with other Laser Mechanisms components.

Operating Principle: The system includes an adjustable camera focusing lens and a sampling prism that can be moved in and out of the laser beam path. It forms a magnified image of the workpiece on a CCD television camera, allowing for precise beam alignment.

Operation: Initial setup involves attaching a camera to the viewer, connecting cables, and adjusting the image orientation. The sampling prism is used to switch between lasing and viewing modes. The focus is adjusted using a knob, and light source repositioning may be necessary for optimal illumination.

Accessories: Required accessories include a high-intensity fiber light source, CCD camera, nine-inch monitor, and mounting hardware, all available from Laser Mechanisms.

Recommendations: For YAG systems, the viewer can be mounted up to 60 inches above the laser lens. For CO2 systems, it should be as close as possible to the laser focusing lens. An interlock switch ensures safety by preventing the laser beam from reaching the optical system when the sampling prism is in place.
