This alignment manual is meant to be used in
conjunction with the “BI-200SM Goniometer
Instruction Manual Ver. 2.0” and training by a
goniometer service technician.
Refer to Page “4-2” in the “Goniometer Instruction
Manual” as a reference for many of the names of
parts on the goniometer system.

Place goniometer on the optical table. Center the four holes on the
base of the goniometer above four holes on the optical table.
•Place the laser rail
foot (LRF) on the
table
•If using a 0.5 meter
rail place LRF near
end of rail, as
shown
•If using longer rail
place LRF 1/3 of
the way from the
end of the rail
•Finger tighten
screws to hold the
LRF and
goniometer to the
optical table

Step 1
Step 2

Slide the laser rail in place and position it. The laser rail can be
even with the LRF or up to 5 mm past the LRF. Tighten the laser
rail in place with the two clamping screws on both laser rail feet.
Tighten the screws completely so that the laser rail will not move
out of place.
After the laser rail is in place and tightened down,
tighten the six screws that hold the goniometer and
laser rail foot to the table. Completely tighten each
screw to ensure the instrument can not be moved out
of place.

Step 4

Look at the goniometer from underneath; there is a small
gap. This is the “X-Y” Table. This must be centered where
the gap is evenly spaced between it and the stainless steel
plate.
Place the 6 mm alignment pins in the gap to
determine if the “X-Y” table is centered. If
the pins do not all fit evenly adjustments to
the table need to be made.
If you do not have pins, an M5 hex key will
work. It should fit evenly all around the
gap.

Step 6

To adjust the “X-Y” Table loosen “7C” and make slight adjustments to
“7A” and “7B” until the alignment pins fit evenly all around in the gap.
They do not need to all be tight or all loose, they just need to all fit the
same way then lock down “7C” again. When locking down "7C", the
table will shift a little so take that into account when making the slight
adjustments.
Place the black
metal pot into the
delrin base.

Step 8

Slightly rotate the black metal pot in place so that knob
“7A” is centered between the two black temperature
control nozzles, located on the back of the black metal
pot, when the goniometer is viewed from the top.
Use the 2 mm alignment pins to center the black metal pot within the
delrin base. Using 3 of the 4 can make it easier to insert. Insert the
tapered ends of the pins in to the gap between the black metal pot and
the delrin base. Gently tighten the three set screws located around the
delrin base to lock the black metal pot in place. The pins should all fit
evenly in the gap.

Step 10

When the three set screws around the delrin base
are tightened down, ensure that knob “7A” is still
centered between the two black temperature
control nozzles.
Remove the 2mm aperture upright
opposite the laser rail and attach the
detector rail

Step 11
Step 12

Attach the detector rail using the two M6x25 flat
head screws that are supplied.
Unlock the detector arm by unscrewing the clutch
release. Rotate the detector arm 180 degrees then
re-tighten the clutch release. Center the detector
arm above the laser rail (as seen in the photo). This
is accomplished by making slight turns of the fine
adjustment knob and viewing the detector arm and
laser rail from multiple angles to determine if it is
centered above the laser rail. Another way: line up
detached detector arm with motor base.
