Optical Measuring Projector

An average optical measuring projector lights up from underneath and ventures the shadow of the measuring object put on the phase through a projection focal point onto a projection screen. Consequently, it's otherwise called a profile projector or shadowgraph. The size of the extended picture is a picture amplified with a right amplification from the measuring object, and the element of the measuring object is estimated by measuring this picture. An optical framework called a "telecentric optical framework" is utilized in the optical comparator so it very well may be extended with precise amplification from any situation on the stage. This telecentric focal point permits you to project the shadow of an article at the right amplification without distorting the picture.
