Working Principle
The light emitted from the projector passes through a condenser lens to illuminate the specimen. The image is then magnified by an objective lens and projected onto the projection screen.
For practical application, the instrument uses single transmitted illumination. The light source passes through a series of optical components onto the working table, and the specimen’s notch contour is clearly projected onto the screen through another set of optical elements.
The image undergoes secondary magnification and reflection to form an upright image, ensuring that the projected contour on the screen corresponds directly to the specimen’s actual placement orientation
