About the Equipment
For detailed information on the Light Source, Ray Table, Adjustable Lens Holder, and Ray Optics
Kit, see the instruction sheets included with those components.
Optics Bench Basic Optics components, such as mounted lenses and the adjust-
able lens holder, snap into the wide central channel of the optics bench. Place the base
of the component on the bench and push down firmly to snap it in place. To move it,
squeeze the tab on base and slide it along the bench.
Components that include a square bolt and a thumb screw are designed to be fasted to
the T-slots on the sides and center of the bench. Slide the bolt into the T-slot, insert the
thumb screw through the component’s mounting hold, thread the screw into the bolt
and tighten it down.
Use the metric scale on the bench to measure the positions of components.
Light Source The included light source can be used on a tabletop or mounted on
the bench. It functions as a bright point source, an illuminated crossed-arrow object, a
primary-color source, and a ray box with up to five parallel rays.
Mounted Lenses The Basic Optics System includes four lenses mounted in hold-
ers. Use them on the optics bench with the light source, viewing screen, and other
Basic Optics components.
Adjustable Lens Holder To use an unmounted lens on the bench, place it in the
adjustable lens holder. It will hold any round lens between 20 and 75 mm in diameter.
Viewing Screen Mount the screen on the bench to view real images formed by
lenses.
Concave/convex Mirror and Half-screen The mounted mirror is concave on
one side and convex on the other side. The radius of curvature of both surfaces is 200
mm. Use the half-screen to view real images formed by the concave side of the mir-
ror.
Ray Table and D-shaped Lens Use the ray table and D-shaped lens on a table-
top with the light source (in ray-box mode) to study angles of incidence, reflection
and refraction.
Ray Optics Kit The ray optics kit is a set of optics components designed for use
with the light source in ray-box mode. To make the rays easy to see and trace, use the
ray optics components on a white sheet of paper on a flat table top. The transparent
storage box doubles as a water tank for studying lenses under water.
