3D Anaglyph Camera Attachment!

Step 2 Gather the supplies.

+ 3D viewing glasses (I used the cyan and red glasses from American Paper Optics). You can also make your own with the filter material below.
+ Black mat board from an art store.
+ Red filter material that matches the filters on the 3D glasses (Roscolux #26 matches typical stock glasses available at a stage lighting store)
+ Cyan (blue) filter material that matches the filters on the 3D glasses (Lee #354 matches the cyan filters on most stock glasses available at a stage lighting store)
+ Some 5mm or 1/4" fiberboard.
+ Beamsplitter (50%) 76x102x3mm (Anchor Optical B27122)
+ Mirror 76x114x3mm (Anchor Optical B20850)
+ Four matching (76mm) posts (optional)
+ A sharp utility knife

If the optics listed above aren't available, try to purchase optics with similar dimensions. Anchor Optics is a cheap source:
Beamsplitters (find a beamsplitter about a 50/50 reflection/transmission ratio)

Try to find a mirror with a matching height to the beamsplitter:

You would need to adjust the mirror and beamsplitter holder to fit the new dimensions (i.e. the grooves should accommodate the thickness and the height and width might change). If you make one with different optics, please let me know how it works.

Hi, I'm new to this and I am wondering: 1). Why did you use such big mirrors and beamsplitters of more than 76x100mm in size? Can't this be done with smaller mirrors and beamsplitters? Like e.g. 35x35mm or so 2). I understand that you need the beamsplitter from a specialised store like anchor (found similar things at www.edmundoptics.com btw), but is it really necessary to have these professional mirrors? Is a normal do-it-yourself-store mirror cut into pieces not good enough? 3). Would there be any reason to use a cube beam splitter instead? Hope someone anwers, this item seems to be old, Gerrit

Hi Gerrit, 1) I just ordered the largest possible optics to capture the most light. You could use smaller mirrors and beamsplitters. Dimly lit images might not look that good. 2) You should use a first surface mirror. Regular mirrors are coated with reflective paint on the back side of the mirror. You will get a double reflection (one reflection of the front of the glass and one reflection off the reflective paint) if you use a regular mirror. 3) I don't see why a cube beam splitter wouldn't work. Good Luck!

Nicely done and great info! Thank you!

I purchsed the following beamsplitter:

Beamsplitter (50%) 76x102x3mm (Anchor Optical B27122)

You might be able to use a beamsplitter that isn't exactly 50%, but I haven't tried it. You can purchase a larger beamsplitter and take it to a glass cutter to reduce the size.
