1.2. Care and Maintenance
Handle the system with care during transportation and unpacking. Banging or dropping the system can damage
the unit or lower system performance. If the system is mishandled during shipment, the optical components may
become misaligned, which could lead to a decrease in image quality. If this occurs, the system will need to be
realigned by qualified personnel. Please contact Thorlabs technical support for more information.
 Do not store or operate in a damp, closed environment.
 Do not store or operate on surfaces that are susceptible to vibrations.
 Do not expose to direct sunlight.
 Do not use solvents on or near the equipment.
 Keep away from dust, dirt, and air-borne pollutants (including cigarette smoke). The system is not
designed for outdoor use. Protect the equipment from rain, snow, and humidity.
 Do not expose to mechanical and thermal extremes. Protect the equipment from rapid variation in
temperature.
 Handle all connectors, both electrical and optical, with care. Do not use unnecessary force, as this may
damage the connectors.
 Handle the optical fiber with care. Mechanical stress can decrease performance and potentially destroy
the fiber. Continual bending of the optical fiber can cause damage. It is important, therefore, to keep
the optical fiber patch cable as straight as possible to minimize bending.
Note: The most common cause of low signal intensity is contamination of the fiber due to airborne pollutants.
To minimize exposure, avoid unnecessarily disconnecting the optical fiber patch cable. In addition, it is advisable
to check the fiber before making other adjustments to the optical system, such as changing the focus or optical
path length. Be sure to check the patch cord for a loose connection, and make sure that the fiber is kept as
straight as possible.
All lasers, especially lasers with resonator cavities that are defined by mechanical tolerances, are delicate
precision instruments and must be handled accordingly. The OCT base unit is designed to withstand normal
transportation and operating conditions. Do not move the system while it is connected and in operation.
