{{BOM}}
In this section, we are assembling the strobe illuminator. This mounts the high-power LED and condenser lens above the sample so the microscope can image the transmitted light.
- Verify the slot of thumbscrew is clean. If strings of plastic are present, use a needle-nose plier to remove them.
- There should be a space between the thinner section and the body of the illumination slider. If not, use a plier to separate them.
- Place the illuminator base(fromstep){qty:1, cat:printedpart} onto the top plate in opposite orientation to the focusing actuator.
- Secure in place with three M3x10mm screws{qty:3} and three M3 nuts{qty: 3} (using a 2.5mm Ball-end Allen key{qty:1})
- Push a M3 nut{qty: 1} into the slot in the illuminator thumbscrew(fromstep){qty:1, cat:printedpart}.
- Screw a M3x20mm pozi pan head screw{qty: 1,cat: mechanic} into the thumbscrew. Use a #1 pozidrive screwdriver{qty:1}.
- Positionate a heat insert{qty:1} in the round hole of the illuminator slider(fromstep){qty:1, cat:printedpart}
- Apply heat to the insert (using a soldering iron{Qty:1}) and use gentle force to push it into position, as described in the guide to use heat inserts.
- Screw the thumbscrew assembly into the heat insert in the illuminator slider.
- Put the illumination slider together with illumination arm(fromstep){qty:1, cat:printedpart}, and align the holes.
- Use a hinge pin(fromstep){qty:1, cat:printedpart} to connect them. Insert it into the rectangular side of the slider.
- It should take a little bit of force to push it through the holes. A needle-nose plier{qty:1} can be useful.
- Use nitrile gloves{Qty:2} to manipulate the condenser lens.
- Make a V cut in the sides of the [20 mm circular lens] Star-LED lens using precision wire cutter{qty:1} as shown in the images.
- Fasten a high-power LED{qty:1} to a heat sink{qty:1} using a double-sided thermal tape{qty:1}, as described in this guide.
- Fasten the assembly to a 20 mm circular lens{Qty:1} using a double-sided self adhesive tape{qty:1}, as described in this guide.
- The final assembly should be as shown below.
- Take the red and black cables{Qty:2} of the illumination assembly and crimp them using two male connectors{qty:2} and a crimper{qty:1} as described in this guide.
- Attach a 2 pin Du Pont connector female housing{qty:1} to it.
- The illumination wiring should be as shown below.
- Position the illumination assembly in the illumination arm. One side of the LED holder has a space for cables.
- Secure the assembly using a cover(fromstep){qty:1, cat:printedpart}, which also have a space for cables.
- Insert the illumination wiring to the cable clip next to LED holder
- Mount the illumination arm assembly to the base.
- Insert the illumination wiring to the other cable clip in the base.
- Connect DuPont female 2-pin connector of the strobe cable to the 2-pin male connector of the illumination wiring. Be careful to connect positive and negative terminals in wrong position.
