Light Source Maintenance
The ImageXpress Confocal HT.ai system is equipped with an external light source connected
to the instrument with a light guide. The light source is a Class 4 high-power laser product with
a rated lifetime of 20,000 hours. There are no user-replaceable parts in the solid-state light
source.
Never attempt to open the instrument or access the high-power laser products. Installation and
service is to be performed by a Molecular Devices Field Service Engineer only.
DANGER!
The external light source is a Class 4 high-power laser product. See
for details on the Class 4 high-power laser product and specific
warning and danger statements for working with the external laser light source.
CAUTION! Do not fold or crimp the light guide. The light quality will diminish, and the
fiber optics can break.
Replacing the Confocal Disk Box
In the ImageXpress Confocal HT.ai system, the Confocal disk box is installed in the Confocal
module housing within the lower enclosure of the instrument. There are three Confocal disk
box configurations. The standard unit contains a single 60 µm pinhole Confocal disk for basic
Confocal protocols. There are two optional Confocal disk box configurations. Each
configuration includes two Confocal disks. For basic and high-throughput Confocal protocols,
there is a dual disk box containing a 60 µm pinhole disk, and a 50 µm slit disk. For basic and
high-resolution Confocal protocols, there is a dual disk box that contains a 60 µm pinhole disk
and a 42 µm pinhole disk. The accessory kit includes the hex keys you use to replace the
Confocal disk box.
