Function and Applications
Experimental goggles with attachments in storage case The experimental goggles were developed for experiments in the field of human biology on sensory and nerve physiology. They are particularly suitable for experiments on optical perception and are also suitable for people who wear glasses.
The glasses are made of soft, supple plastic. The assembly of the various diaphragms, filters and coloured lenses in the goggles is very easy to carry out by means of a hinged goggle stem and screw rings. Ventilation domes prevent fogging, and the glasses are attached to the head with a textile stretch band.
Together with the enclosed picture and colour templates, various experiments on spatial and colour vision can be carried out.
All parts are safely and dust-protected in a practical, stackable plastic case with foam inserts.
