The opaque projector is a relatively old device that is commonly known by
many different names including episcope and epidiascope. It is used for the
purpose of displaying opaque materials. This is done with the use of a
brightly shining lamp that shines light onto the opaque object from above.
Here, it is essential to point out that the projector itself is loaded with
a unique network of mirrors, imaging lenses and prisms that are used in
combination in order to get the right focus of the image. The object is
then displayed on a conventional screen.

problems in the reading of the objects and furthermore does not cause any
What are these types of projectors used for? Basically they are used to
display the images of drawings, book pages, leaves, mineral specimens and

canvas or any other drawing surface. Similarly, these projectors can be
used during lectures and seminars. Today you will be able to find them in
the overhead model as well which adds convenience for users.
