Making the Safety Interlock Connections
The MCLS series of laser sources are equipped with a remote interlock connector located on the rear panel. All units have this feature regardless of their FDA
and IEC classifications. In order to enable the MCLS source, a short circuit must be applied across the terminals of the Remote Interlock connector. In practice
this connection is made available to allow the user to connect a remote-actuated switch to the connector (i.e., an open door indicator). The switch (which must
be normally open) has to be closed in order for the unit to be enabled. Once the switch is in an open state, the MCLS source will automatically shut down. If
the switch returns to a closed condition, the MCLS source must be re-enabled at the unit by pressing the "Master Enable" switch.

Laser Safety and Classification
Safe practices and proper usage of safety equipment should be taken into consideration when operating lasers. The eye is susceptible to injury, even from very
low levels of laser light. Thorlabs offers a range of laser safety accessories that can be used to reduce the risk of accidents or injuries. Laser emission in the
visible and near infrared spectral ranges has the greatest potential for retinal injury, as the cornea and lens are transparent to those wavelengths, and the lens
can focus the laser energy onto the retina.
Safe Practices and Light Safety Accessories
Thorlabs recommends the use of safety eyewear whenever working with laser
beams with non-negligible powers (i.e., > Class 1) since metallic tools such
as screwdrivers can accidentally redirect a beam.
Laser goggles designed for specific wavelengths should be clearly available
near laser setups to protect the wearer from unintentional laser reflections.
Goggles are marked with the wavelength range over which protection is
afforded and the minimum optical density within that range.
Laser Barriers and Blackout Materials can prevent direct or reflected light
from leaving the experimental setup area.
Thorlabs' Enclosure Systems can be used to contain optical setups to isolate
or minimize laser hazards.
A fiber-pigtailed laser should always be turned off before connecting it to or
disconnecting it from another fiber, especially when the laser is at power
levels above 10 mW.
