Includes all items in the Basic Optics System, plus a wider assortment of optics components supporting polarization, interference, and diffraction.


The Basic Optics Systems are easy to use, ruggedly designed, and an economical choice for the optics laboratory. The Basic Optics System supports 17 included experiments in both geometric bench optics and table-top ray optics experiments with the Basic Optics System II including all of the Basic Optics System components and more.

The Basic Optics Systems were built to be flexible, versatile and easy to use. Large 50 mm diameter optics components are mounted in protective holders that snap directly onto the aluminum track, and they are easy to slide and reposition. Built-in metric tape makes measurements of image and object distances quick and accurate for both lenses and mirrors. The versatile Light Source doubles as a table-top ray box, for studies in reflection, refraction, color addition, and Snell's Law.

Special Features

  • OpticsTrack (1.2 m):Lens holders, mirrors, light source, and viewing screen snap into this rugged aluminum optics track. The metric tape makes position measurements easy. Optical alignment is always a snap.
  • Light Source:Has a lighted crossed arrow target with metric scale for focusing images through lenses or using with the concave mirror. Acts as a point light source, 1, 3, or 5parallel rays, orred-green-blue rays.
  • Lenses:4 - 50 mm diameter lenses - focal lengths +100, +200, +250, -150 mm mounted in protective holders
  • Concave/Convex Mirror:50 mm diameter plastic mirror with reflective surface on both sides. Includes "half-screen" upon which the image is focused.
  • Adjustable Lens Holder:Use your own lenses (from 19 mm to 75 mm in diameter) or choose from our lens sets.
  • Ray Optics Kit:Concave/convex lenses, concave/convex/plane mirrors, acrylic rhomboid prism for spreading white light and refraction experiments, hollow lens for teaching the lensmaker's equation. Storage tray functions as a water tank for the hollow lens.
  • Ray Table:Two-piece construction allows the table torotate for studying Snell’s Law or the Law of Reflection. Includes D-shaped acrylic lens.
  • Viewing Screen:White plastic screen snaps into the optics bench - the position of the screen is visible on the bench scale.
  • Experiment Manual:The experiment guide includes 17 ready-to-use optics experiments with teacher notes and sample data.
  • Storage Box:Everything fits neatly into the protective storage box, with the exception of the 1.2 meter Optics Track.
  • Storage Box:Everything fits neatly into the protective storage box, with the exception of the 1.2 meter Optics Track.
