ZAP-IT® paper provides a quick, thermally based estimate of beam image and size. The paper is thermally sensitive over a broad spectrum from ultraviolet to infrared. It is simple to use. Hold or fasten it in the beam path at the point where the beam imprint is to be recorded. Pulse the laser and a permanent visual record is produced, corresponding to the energy distribution within the laser beam. If the laser is continuous wave (CW), you can create a short pulse by Q-switch, mechanical chopper, or by physically turning the laser on and off rapidly.

Specifications:

• Pulse Width Range: 1 ns to 30 ms
• Power Level Range: 5 mj/cm² to 20 j/cm²
