Technology Summary

Education Kits » EWSY-5 Abbe Imaging and θ Modulation


This optical rail, 1M long, carries general slide, 1-D adjustable slide 2-D adjustable slide; and 3-D adjustable slides. It comes equipped with holders, optical components and light sources. Many kinds of experiments can be performed on the rail, covering geometrical optics, physical optics and information optics. Such as measuring focal lenth, Fresnel diffraction of single slit, Abbe imaging principle and optical spatial filtering etc. With compact construction, steady rigid-frame, well expansibility and modest price, this equipment is appropriate for basic optical experiment-teaching at institutions of higher education.
