The laser/galvanometer system comprises a Class 3R laser (532 nm (visible
green) laser source, 5 mW maximum continuous (CW). The laser beam is
directed into the imaging chamber by two computer-controlled mirrors.

WARNING
WARNING! A laser beam can be harmful to the eyes. ABSOLUTELY DO
NOT look directly into the laser beam when the laser is turned on. Be aware
that laser light can be easily reflected off of shiny surfaces and that this
reflected light can be dangerous. When the laser is on, remove all watches
and jewelry when placing hands in the imaging chamber.
The laser/galvanometer system provides field of view alignment targets for
reproducible specimen positioning and structured light for 3D contouring and
auto-focusing.
The crash avoidance system uses a scanning laser to determine the subject
height and verify that it is within acceptable limits. This system prevents injury
to specimens and damage to delicate optical components such as the lens
window or the illumination diffusers for field of view A only.
You are prompted at the start of each imaging session to input a sample height
estimate. If the estimate is in error, the crash avoidance system protects the
specimen. Alternatively, the system can be configured to automatically
determine the sample height.

IMPORTANT
ALERT! Do not block the ventilation openings on the base or position the
system too close to a wall so that the exhaust flow is obstructed.
The base is equipped with four casters that enable you to move the instrument
. For more details on how to move the IVIS Spectrum, see
