3. Place the assembly into the benchtop organizer for storage.
5.2.13 Polarization Mount Assembly
1. Unscrew the retaining ring from the LMR1 (LMR1/M) optic mount.
2. Take one polarizer from the box. The polarizers have a flattened edge which is parallel to the transmission
axis. Additionally, it is covered by two layers of adhesive film. It is very helpful to place a piece of sticky
adhesive tape over the edge of this film. When removing the tape, the protective film is then pulled off as
well.
To get a grip on the protective film, it might be necessary to cut along the flat edge of the film
with scissors and use tweezers to peel the film off. (Note: this is all best done while wearing gloves to
keep the polarizer surfaces clean.) The result can be seen here:
3. Remove the retaining ring from the short SM1L03 lens tube. Then put the bare polarizer sheet in the
SM1L03 lens tube and fix it into position with the retaining ring.
4. Attach the lens tube to the LMR1 (LMR1/M) mount. The orientation of the polarizer in the mount will be
random (this is intentional, for pedagogical purposes).
5. Add label
“Polar I” to the optic mount.
6. Place the assembly into the benchtop organizer for storage.
7. Screw the retaining ring from the RSP1D (RSP1D/M) rotating polarizer mount all the way down to the
inner lip (this broadens the inner lip). Repeat the previous steps and remove the adhesive films from the
polarizer sheet and insert it into the polarizer mount against the retaining ring. Use one of the spare
retaining rings (left over from previous assembly steps) and fix the polarizer into position. Thus, the
orientation of the polarizer will be random in the mount. This is also intentional, for pedagogical purposes.
8. Add label
“Polar I” to the optic mounts.
