Zeiss developed various models of the Verant over the years. My model is an early model with serial number 5408. This model was manufactured from c. 1905 and comes with a black cardboard box. The viewer is suitable for stereoview sizes up to 9 x 15cm. Later models supported sizes up to 9 x 18cm and were sold in a wooden box with a set of sample glass stereoviews.
The Verant consists of three parts: a base plate, the stereoview holder and the lens carrier. A white slide-out plate in the base plate provides a neutral background when viewing glass stereoviews. Like the Ernemann Universal Stereoscope, the holder and lens carrier can be set at an oblique angle which improves the viewing experience. It can be adjusted in an angle from 0 to 90 degrees.
The Verant can be used for viewing glass stereoviews and paper stereocards. The stereoviews can be placed in the holder and fixed by two metal clips on both sides of the holder. This is especially useful for paper stereocards that tend to curl. The clips will keep them flat.
The two 100mm lenses are of high quality and can be focussed by displacing the lens carrier. The distance between both lenses is adjustable. The lenses can be unscrewed from the carrier and stored in special holders in the cardboard box.
I am very pleased with this viewer. The solid construction, good lenses and smooth operation makes it a high quality stereo viewer. The only drawback is its open construction. This contributes to its versatility to support multiple formats but makes it prone to reflections.
