If the Mosaic is supplied with a laser source it will incorporate an interlock safety system to protect the users of the
system.
The Mosaic contains no user serviceable parts- do not attempt to disassemble the system or the enclosure.
Disassembly is only to be performed by trained and certified Andor Service Personnel. Removal of any housing
component or panel may result in exposure to hazardous radiation. As the housing is not to be accessed for operation
or user maintenance the panels are not interlocked. The only exception is the Mosaic Infinity which allows the User to
change the loaded Filter Cubes. The Filter Cube Access Panel is interlocked with a redundant, failsafe sensor system.
Please refer to Section 6.5 for the correct procedure to change Filter Cubes.
The User Interlock System comprises of a set of sensors which are used to detect the state and configuration of the
Microscopy System including the Microscope Eyepiece prism, the transmitted light arm on inverted microscopes and
the presence of a stage cover if one is installed. Additionally the Beam Splitter/Dichroic plugs are interlocked. This is
designed to prevent the user from being accidentally exposed to the potentially high level of laser radiation emitted by
the Mosaic into the microscopy system. The system is directly linked to the laser source to cease emission of any laser
light if any of the following conditions exist:
•
The eyepiece prism is in any position other than 100 % camera port
•
If the transmitted light arm is not in the upright position
•
If an installed stage cover is not present
•
if any Beam Splitter plug is removed or if the Infinity’s Filter Cube access panel is open
The Interlock Loom provides an additional connection point to allow a Remote Interlock (e.g. a Laboratory Door) to be
interfaced directly to the safety system.
The laser source monitors the interlock loom for continuity with a low voltage signal and ceases laser emission if the
circuit is broken at any point.
