Assembling the Lens Tubes: 5° and 10°
Tools Required:
• #2 Phillips head screwdriver
1:
Place the lens tube assembly (1) on your work surface. Align the assembly so that the colour
frame grooves are to your left.
2:
If you are assembling a 5° tube, attach the handle (10) as shown in
Figure 20
, using the screws
(12), washers (13), and backing plate (11).
3:
Install the required lens as shown in

in the tube using required
bumpers (4), screws (7), nuts (8), and washers (9). The side of the lens with the fresnel grooves
should face the front of the tube. The smooth side should face the rear.
Cleaning the Polymer Lenses: 5° and 10°
Remove dust with a blast of oil-free air. If this is not sufficient, follow the instructions below.
1:
Dip the lens in a clean isopropyl alcohol/water mixture (9 parts water to 1 part isopropyl alcohol).
2:
Use a soft moistened nylon bristle brush to wash the lens’ smooth side in a linear (non-circular)
motion.
3:
Use the same brush to lightly wash the ridged side of the lens by following its ridges.
4:
Dip the lens in a clean isopropyl alcohol/water mixture (9 parts water to 1 part isopropyl alcohol).
5:
Use an air gun to dry the smooth surface. Use an air gun to dry the ridged surface. Use the air
stream to move the liquid away from you. Using this method, remove as much liquid as possible.
Inspect the lens for dirt. If necessary, repeat the entire process.
WARNING:
Handle polymer lenses by their edges only. Never rub anything dry on a
polymer lens. Do not use glass and window cleaners on the lens. This will
damage the lens.
