Planox was a trademark for stereoscopes produced by the company of Alexandre Plocq. The firm was founded in 1895 and initially specialised in the manufacture of wooden components and cameras. Plocq entered the stereoscope market relatively late, possibly under the influence of his son Albéric Plocq, who joined the company around 1912.
In 1921 the company introduced the Stéréoscope Magnétique, a tray-based stereoscope distributed under the Planox name. Several additional stereoscope designs followed. Planox stereoscopes continued to be sold until after the Second World War.
Planox stereoscopes were also manufactured for the German company Franke & Heidecke and sold under the name Heidoplast.
