Title: Nicolet 6700 on-axis interferometer optics
Issue:
The laser beampath through the beamsplitter and interferometer will
change from Off-Axis to On-Axis starting with 6700 serial number prefix
APW. This change affects the location of the interferometer laser
pick off mirror, the beamsplitter style, laser detector preamp and the
laser detector preamp cable.
Also, there is a small cosmetic change to the beamsplitter manufacture
process. This is described in detail with a picture on Page 2.
Background:
Magna 550, 750, 560, 760 and Nexus 470, 670, 870 models all used
On-Axis interferometer optics. The Nicolet 6700 changed the laser
beampath to Off-Axis for the Continuum XL and Micro Probe microscope.
Off-Axis optics placed the laser signal and laser preamp off the
center of the beamsplitter. This provided consistent illumination to the
pixels of the array detector. These microscope models are either discontinued
or in retirement. Off axis interferometer optics do not add any
other value to the 6700 model. Therefore, the Nicolet 6700 will migrate
back to On-axis beamsplitter optics.
Upgraded systems:
Magna, Protégé and Nexus systems that have been upgraded to the
6700 are all On-Axis interferometer systems. The Magna / Protégé upgraded
6700 systems have the AKL serial number prefix. This change
will not affect the upgraded systems since they are already On-Axis.

Solution:
Factory Communication
Nicolet 6700 and 8700 systems with Serial number APW and forward will have On-Axis interferometers,
laser preamps and beamsplitters. This change will be transparent to most customers.
The greatest impact will affect what part to order when placing service orders for interferometers
and beamplitters. There should be no need to change systems in the field from Off-
Axis to On-Axis.
Visual change to beamsplitter mask
The On-Axis beamsplitter mask has been updated. The new on-axis beam splitters will show
one slight visual difference from the older “Magna” and “Nexus” on-axis beam splitters. A thin
uncoated slot will run from the central laser hole to the right side (pictured below). This is due
to the use of a new metal mask for production, which greatly improves the yield in beam splitter
manufacturing. This will not affect performance since the slot is in the shadow of the laser detector
arm and the laser pick off mirror. The Solid Substrate beam splitter will not change. The
Si beamsplitter has a drilled hole for the laser window with no slot, regardless of part number.
Service LRU part numbers
Interferometer service orders for new Nicolet 6700 systems with On-Axis optics, AKL and
APW serial number prefix, should order the On-Axis Nexus interferometer and
beamsplitters.
