I have included file sizes in the image links.  Please take a moment to check these sizes before you begin downloading images for viewing.  Several of the JPS files are very large and will be painful to download over a modem link.

The images are presented in cross-eye and anaglyph format.  If you prefer a different format or size, please give the Stereoscope applet a try.

Java Stereo Viewer

Many of these pages use a Java Stereoscope applet by
Andreas Petersik
. It made a Java convert out of me and I highly recommend it.

 Off The Shelf

The standard viewer sports:

  • Lens diameter of 32mm

  • Lens focal length of 75mm

  • Viewer lens opening of 30mm

  • Fixed interocular distance of 64.5mm

  • Viewing apertures that are 55mm square

  • Fixed focus


The plastic mounts are 3mm thick with 52mm square apertures placed 65mm apart.  They are composed of two identical plastic halves that are designed to press together with the film in between them.  I consider these mounts to me nothing more than expensive raw materials.  My preferred mount comes from Rocky Mountain Memories and is 80x132mm with several available film apertures.  These cardboard mounts vary somewhat in thickness, but range from 1.25mm to 2mm.

Showing the curved diffuser panel and the very evident thumb groove. When you pry the diffuser panel off, you can see the shiny interior. Here you can see the lands and valleys that are supposed to hold the halves together.

The diffuser on the viewer is an interesting piece.  It is pressed on to the back of the viewer and usually held in place with a few drops of solvent. The diffuser carries the viewer's curves and grabs the light reasonably well.  As I considered how to provide this viewer with an internal light, this cavernous enclosure (80x170mm) is what caught my attention.  

Several people use thin fluorescent panels to light their viewers.  To do so, they commonly remove the diffuser and tape the light source in its place.  The result is a wall or battery powered illuminated viewer with a lot of bits sticking out.  I wanted to see if I could get that thin light source mounted completely inside the removable diffuser panel. 

The idea of modifying this steal-the-light viewer into a fully illuminated viewer without changing its external appearance seemed a fun challenge.  But could it be done?    Next
