Non-Variable Vertical Tranaglyph™ Slides (70 Series) are designed for use in activities involving vertical vergence and binocular alignment. These red/green prismatic tranaglyph slides provide fixed vertical prism demands ranging from 0.25Δ to 2.00Δ in 0.25Δ increments, allowing practitioners to select the appropriate level for their application.

The high-contrast red/green targets are printed on durable frosted vinyl for clear presentation and consistent image separation when used with red/green viewing filters. The fixed-demand design provides a convenient and repeatable method for presenting a range of vertical prism separations.

Each slide measures 5.5" x 10.5" and is compatible with the Bernell Polachrome Trainer and other suitable tranaglyph viewing systems.
