Where do i get half-silvered mirrors?

[Tonpole]

I cant seem to find them on google/ebay/amazon.

Half silvered ?

Do you mean 50-50 mirror ? (50% transmission 50% reflection) for a stereo mirror rig ?

[Tonpole]

yes, 50/50, half silvered, beamsplitter, i guess it goes by many names.

It depends on your location i guess. Have you tried googling telepromter mirrors? Be sure to get glasses ones. Usually plastic mess up polarization but i think there are exceptions though.

It wasn't easy for me. I didn't want to spend the outrageous prices they have at teleprompter.com, but thats up to you. I settled for a one-way mirror, with more reflectance than visible light transmittance. Compensating with one monitor being brighter, high contrast has yielded acceptable results. Im quite impressed with the 3D effect for my planar 3d stereo mirror rig. I got mine @ a local glass shop, look up in your area and ask for one way mirrors, with the mirrored surface on the front side (prevents double reflection).

I paid $65 bucks or something for a 23 by 19 inch 1/4 inch thick one way mirror (real glass). I also tried mirroring film (tinting film) before this, and it messed up the polarization. You should be able to find my forum thread on here, with my experience building this thing.

Actually i dont need to preserve polarization for my purpose, does the film work well anyways?

You can find the procedure online for mirror making. I have also seen some alterations to the procedure that allow for half silvering. You may want to look into "Tollin's Reagent". It's used in chemistry to test for the presence of aldehydes and when an aldehyde is present, silver will form on the inside of the glass vessel you are using. There are other ways to precipitate silver onto glass besides Tollin's Reagent but they are all very similar. Here are some links if you are interested.

I can't remember where I found the page about diy half silvered mirrors but I'm pretty sure they just reduced the concentration of silver nitrate by about half or only left the silver nitrate on the glass for half the time.
