SANKOR NEW CINEMASCOPE 5e Anamorphic Lens Complete Restoration Part I (One)

In the video i'm sharing my tested method for fixing the balsam separation in my case for some anamorphic lenses elements. When you get the rainbow you know what it is. Is called balsam separation. The original thing is most probably a natural compound since the smell is like Fir Three. The original compound might be available but my choice is Epoxy UV compound used for mobile screens glue. It is sold like this and usually comes with a little UV LED light.

If you consider doing it please follow some tips.

1. When you heat the lens make sure you gradually increase the temperature. I started the steamer and when a bit warm i stopped it for few minutes and then again and again until leaving it to boil for 2-5 minutes. This is important since if you put the glass directly under heat might crack. As well leave it gradually to cool down.

2. Handle the lenses with care. There is not too much care.
3. Mark somehow the original position to know it later.
4. Clean it with Methanol, IPA, or lighter fluid. White spirit will work as well.
5. Make sure you clean it very well then against a light source get rid of dust. You can use micro fiber cloth for glasses but the dust is the most difficult to get rid of.
6. The last touch is the most important. Blow on it and with a sensor cleaning swab is easy and gentle to remove any remaining particles.
7. The blue liquid is windscreen washing liquid.
8. The foam can is Glass Cleaner.
9. Make sure you align the elements and secure them before the UV Light.
10. When you handle the lens make sure your fingers are clean. Excess glue It will come out on sides and might touch your fingers and then touch other parts. Before putting the V light make sure the glass is clean. If happens Acetone will help but i'm not sure if will affect the lens coating.
11. Few seconds exposing to UV light and is done.
12. When you put the UV light make sure you press a bit the elements for the last time without moving them. Gentle.
13. With luck...IF YOU TRAP DUST, BUBBLES, NOT ALIGNED you are screwed! Make sure the glass have room temperature.

I don't think you will be able to remove the elements ever again so is one chance. If you use the original optical compound is ok but might be hard to find.

DO IT ON YOUR RESPONSIBILITY in a clean place. On daylight might be even better. Take your time for every step. Rehearse every step in your mind before and keep the tools, and something to wipe your hands close.

If you have more questions ask. Read and watch before you ask.

Good luck.

AGAIN...THERE IS NO TURNING BACK to separate them. Is permanent.
