【Product Description】

Introductory-level optical system that explains how rays emitted from the light source are converged onto the slide form image on the screen after passing through the lens at a certain focal distance.

【Overall Advantages to Users】

  • Specialized in measuring focal distance of the image projected through a double-convex lens and magnified on the screen.
  • Portable apparatus with a battery powered LED light source.
  • Better storage and portability because all the components can be stored in a Gratnells’ case that comes with the product.
  • Equipped with four types of color filter slides with different graphics that provide better visibility of the image that is horizontally and vertically reversed when projected on the screen through a double-convex lens.

【To all users】

  • The zero-point of the scale is designed to be in the center of the rail when assembled. Therefore, if the lens is mounted on the zero-point, users can instantly read the distance between the lens and screen, as well as the one between the lens and light source.

【To teachers】

  • Simplicity and compactness of the design and configuration of the product contributes to shorter time and less efforts required in preparing experiment, as well as less space needed to carry out the experiments.
