• In the LCP01 cage plate, the LED will get sandwiched in-between two SM2RR retaining rings. First screw in one SM2RR only 1 mm deep.
• Next place the LED above it.
• Finally tighten down the second SM2RR using the SPW801 adjustable spanner wrench. The SPW801 can be opened until its width matches the SM2RR diameter, the separation between the ring's notches.
• In the LCP02 cage plate adapter, screw in on SM1RR 3 mm deep.
• Carefully (use lens paper unsparingly to protect the lens surface) place the 25 mm plano-convex lens above it, with the hemisphere facing down yet not touching any potentially damaging surface.
• Tighten down a second SM1RR using the SPW602 spanner wrench, whose guide flanges sit in the ring's notches to prevent any scratching of the lens's optical surface.
• Attach the LCP01 cage plate (holding the LED) to the LCP02 adapter (holding the 25 mm condenser lens), using four ER1 rods secured by eight 8-32 set screws.
• Affix a TR2 optical post to the LCP01 cage plate (holding the LED).
• Slide in the LED assembly along the optical rail.

Power the LED light source:

• The red LED will be connected to a DC power supply. Ensure that the current limit on the power supply (CH1) is set to a value below 0.5 A.
• Connect channel CH1 to the red and black threads of the LED, using alligator clip cables.
• Turn on the power supply, and press its Output button to light the LED.
• Adjust the LED brightness using the power supply's Voltage knob.

• Tighten the R1DS1N 1951 USAF test target in-between two SM1RR retaining rings inside the SM1L10 lens tube, using the SPW602 spanner wrench. (This procedure should be reminiscent of the insertion of the 25 mm hemispherical lens in the cage plate adapter.)
• Slide in the lens tube through the SM1RC slip ring. By rotating the lens tube, you will be able to modify orientation of the object.
• Affix a TR2 optical post to the SM1RC slip ring (holding the USAF target).
• Slide in the object assembly along the optical rail.

• Tighten the LB1811 biconvex f = 35 mm lens in-between two SM1RR retaining rings inside the CP02 cage plate.
• Affix a TR2 optical post to the CP02 cage plate (holding the lens).
• Slide in the lens assembly along the optical rail.

• Affix a TR2 optical post directly to the CCD camera plate using the 1/4-20 set screw.
• Slide in the camera assembly along the optical rail.
• Connect the CCD to the computer using a red ethernet cable.
• Power up the CCD using the Calrad 45-601 power adapter.
