Page 7: Introduction
Be careful to observe the information in the Environmental Requirements section that alert you to the hazards and the laser beam path you can expect while running the XLR8. The XLR8 Scan Head is extremely intricate, and since it consists of galvanometers that reflect the laser beam, it can be hazardous if certain precautions are not taken.

Page 14: Safety And Warnings
Laser Hazard The first consideration in a safety analysis is the laser mated to the Nutfield Technology X/Y Analysis Scan Head. The hazard level of the laser is roughly indicated by the Laser Class label that is on the device.
Page 15: Laser Shutter Installation
XLR8 Nutfield Technology The Nutfield Technology X/Y Scan Heads provide the ability to aim the laser beam over a roughly pyramidal volume. The divergence of the focused beam beyond the focal point, which is a function of the lenses selected and their positions, can cause radiation to exit the pyramid.
Page 16: Installation Safety Requirements
Refer to Section, Safety and Warnings, Section 3. 3.3 Safety Precautions during Usage To maintain the necessary safety during usage of the XLR8 Scan Head, please take following actions: 1) Please avoid any mechanical tension to the connection cables.
