Chopper Head
The Model 3502 Optical Chopper Head (Figure 10 and Figure 11) may be
secured to standard optical benches using
¼” -20 or M6 bolts. The bolts pass
through the mounting plate perpendicular to the plane of the optical bench. This
mounting method provides the advantage of allowing the wheel to be rotated by
loosening the
¼” -20 set screws on the side of the motor mount. Do not over-
tighten the set screws.
The Model 3502 Optical Chopper head may also be mounted on standard ½”
optical bench rods. First, loosen the two ¼” -20 set screws. (These secure the
head to the mounting plate by compressing on the dowel.) Remove the dowel
and mounting plate assembly. Insert the
¼” -20 knob (supplied with the
Chopper) into the base of the head. This knob is inserted into the same hole
occupied by the dowel. Slide the motor mount onto the ½” optical bench rod and
hand- tighten the knob. Do not over-tighten.
