Lab Over Head Projectors
3-Element Vari Focal technology
Overhead projector are equipped with a vari focal objective. In order to focus the projector image using a vari focal objective the focal length is changed by adjusting the mobile lenses. Thus the distances between the objective and the working top as well as the projection angle remain constant.
The advantages :
At any image size the projection is free of coloured fringes. Neither the position of the objective nor the lamp housing need to be adjusted.
OHPs from projection ( India) guarantee you clear, focused projections at any image size. Adjusting brown or blue fringes now belongs to the past.
