the unit will not be damaged in shipment, observe the
following rules:
➀ The carton must be strong enough for the item
shipped.
➁ Make certain there is at least two inches of packing
material between any point on the apparatus and the
inside walls of the carton.
➂ Make certain that the packing material can not shift in
the box, or become compressed, thus letting the instrument come in contact with the edge of the box.

012-06557A Optics Table
Introduction
The PASCO OS-8536 Optics Table includes:
– cylindrical lens
– ray table
– ray table base and mounting hardware
The lens, ray table, and ray table base are designed to be
used with the Optics Bench, Ray Optics Kit, and Light
Source which are included in the OS-8515 Basic Optics
System.
Cylindrical Lens
The Cylindrical Lens is a “D”-shaped piece of clear
acrylic plastic. The lens is one inch (2.54 cm) thick, and
the radius of curvature is one inch (2.54 cm).
Ray Table
The Ray Table is a metal disk six inches (15.24 cm) in
diameter with a degree scale printed on both sides. In addition, the center of one side has a Cartesian grid marked
in millimeters (mm). The Ray Table has a hole in its center which fits over the post on the top of the Ray Table
Base.
Ray Table Base
The top side of the Ray Table Base has a ring of magnetic
material that holds the Ray Table in position when the
Ray Table is placed on the post on the top of the table.
The mounting hardware on each leg of the Ray Table
Base consists of a square nut and a thumbscrew. The
square nuts fit into the T-slot on each side of the Optics
Bench that is a part of the OS-8515 Basic Optics System.
Tightening the thumbscrews holds the Ray Table Base in
position when it is mounted on the Optics Bench.
Mounting the Ray Table Base t o the Optics
Bench
Loosen each thumbscrew by turning counter-clockwise.
Leave the square nut on the end of each thumbscrew. Attach the Ray Table Base to the Optics Bench by inserting
the square nuts into the T-slots on each side of the track.
The base can be moved to any position along the track
while the thumbscrews are loose. Tighten the thumbscrews to secure the base in position.

About the Experiments
Experiments 1, 2, and 6 use the OS-8536 (Cylindrical
Lens, Ray Table, and Ray Table Base), and the Light
Source and Optics Bench from the OS-8515 Basic Optics
System.
Experiment 3 Prisms Rhombus
Experiment 4 Reflection Three-Surface Mirror
Experiment 5 Snell’s Law Rhombus
Experiment 7 Refraction Convex Lens, Concave Lens
Experiment 8 Lensmaker’s Equation Concave Lens
Experiment 9 Apparent Depth Convex Lens, Rhombus
Experiment 3 through 9 are described in more detail in the Instruction Manual and Experiment Guide for the OS-8515
Basic Optics System.
The other experiments use the Ray Table and Ray Table
Base of the OS-8536 and the Light Source and Optics
Bench of the OS-8515 and the following additional
equipment from the OS-8515 Basic Optics System:

Purpose
The purpose is to determine the relationship that exists

between the angle of incidence and the angle of refraction for light passing from air into a more optically dense
medium (the Cylindrical Lens). The second purpose is to
determine whether the same relationship holds between
the angles of incidence and refraction for light passing
out of a more optically dense medium back into air. That
is to say, if the light is traveling in the opposite direction
through the lens, is the law of refraction the same or
different? In this experiment, you will find the answer to
this question.
