How to clean Rangefinder Beamsplitter Mirror Minolta?

The best way to clean a rangefinder mirror is by using alcohol wipes. These will remove any dust particles from the lens but it won’t affect the optical quality of the camera. If you want to remove fingerprints from the rangefinder then you should use a microfiber cloth.

Disassembling Focusing Wheel

When you take apart your camera, you should replace the gears if they’re worn out. Citric acid is a great cleaning agent. Ultrasonic cleaners are good for cleaning metal.

Gears are used to make things work. A gear train is made up of the main cog, an intermediate cog, and a final cog. Sometimes gears get worn out because of too much stress or torque. You can use your fingers to turn the gears instead of using a wheel.

The main cog is connected to a focusing wheel. Carefully take out this screw and make sure not to damage the slot. This will disconnect the main cog from the other cog underneath it. Remove the main cog and you’ll see a spring. This makes turning easier because it acts like a suspension. Adjust it if you know how to do it. I’ll just leave this alone if you want me to.

You can remove the plate by removing these screws. Note that there is one flush screw. Don’t forget to replace it. The largest cog can be removed after you’ve extracted two big ones. We had to heat the screws before we could pull them safely. Don’t lose the washer underneath.

Relays are the most important part of any mechanical device. They control everything else. They are used to switch power on or off. They are also used to start motors. In this case, the relay is used to open and close the shutter.

When the shutter opens, light enters the camera. This causes an electrical charge to flow through the wires. This charge travels along the wire to another place. At the other end of the wire, there is a metal plate called the contactor. The contactor is connected to the shutter release button.

When the shutter is closed, the contactor closes the circuit. This means that when the shutter is released, the shutter opens.

Disassembling Rangefinder Assembly

Camera lenses are made up of many parts. Some of these parts are easy to replace while others are more difficult to repair. You need to be careful when handling the lens assembly as it may break if you aren’t careful enough.

Take lots of pictures before you start taking things apart. You should write down what each part does so you won’t lose any information when putting it back together. The viewfinder prism block is secured by a bracket connected to the vertical correction lens. You can remove this by unscrewing the screws.

Remove the housing of the vertical adjustment bracket. Make sure that the beam splitter won’t scratch the bare glass opposite. Leave the prism/beam splitter on the main chassis.

Screws must be removed carefully. The rangefinder assembly should be cleaned after removing screws. Factory made adjustments must be done by a professional.

Here’s everything. Carefully remove all the joints and flush them with solvents. Use the best watch repair oil available and apply it with a needle’s end. Massage the joint until it’s coated evenly. Clean the cam and flush it with solvent.

This is the bare spot that transmits light well. Cleaning it helps give you a clear image. You should take as many photos and notes as possible so you’ll know how to align this properly after removing it or if it gets dislodged.

Most, if not every Japanese camera has a round rangefinder patch because there’s no rectangular opening between this and the vertical adjustment lens.

A mask can also be used to cover up the rangefinder patch.

This is how to remove the beam splitter block. Apply pressure to it until it comes out. Clean all of the bare surfaces. Re-install the thin baffles at the front end.

Diopters are removable lenses that allow us to see things more clearly. There are two types of diopters: single-element and multi-element. Single-element diopters are made up of a single lens element. Multi-element diopters consist of several elements.

To remove the diopter, you must first unscrew the flash sync arm. Then, you need to carefully pull out the diopter. Make sure that your hands are steady as you do this. When you’re done, clean the frame lines thoroughly and reattach the diopter.

This is the most difficult part of this project. We need to be very careful while working on the rangefinder assembly. Use plenty of Q-Tips and naphtha to remove any dirt or dust. Don’t use too much solvent. Handle the rangefinder assembly carefully.

Conclusion

A clean rangefinder is the mark of a successful job. You’ll see a big difference once you peer through it. Most of the Nikon rangefinder patches are dim because of deterioration and dirt.

A prism is made up of two mirrors facing each other. The light passes through both layers until it reaches your eye. You can clean the mirror by rubbing it with a cloth dipped in alcohol.

Don’t use water as it might damage the surface. Use an oil-based cleaner if you want to remove any dust particles. Once cleaned, place the mirror back into its original position.
