| Magnetic
Prism Set with Light Source |
|
|
|
Perform refraction experiments
and study the behavior of light after passing through different shapes.
Each piece has a magnetic back for mounting on a magnetic chalk or marker
board. The bottom of the pieces are painted white so that the ray of light
can be easily seen, and the sides are polished for extra clarity. Clear
acrylic prisms measure 6" thick. Set includes seven lenses
(equilateral, isosceles, semi-circular block, double concave, double
convex, plano concave, and plano convex), laser source with magnetic
backing and storage box with cut-out foam storage spaces for each piece. |
| Laser
Optical Disc Set |
|
|
|
An excellent and economical set
for introductory ray optics! The laser ray box projects one, three, or
five parallel bright beams and is equipped with a momentary switch for
safety. Includes a substantial vinyl template with a degree circle and a
linear scale forming the optical disk; seven clear acrylic optical
elements; and a mirror with adjustable curvature for investigating
refraction, lenses, prisms, and mirrors. The bottoms of the acrylic
elements are frosted to show the ray paths inside. Includes manual and
storage box. |
| Refraction
Tank with Laser |
|
|
|
A self contained unit to measure
and study refraction of light. Incident and refractive rays are easily
seen and measured. Light rays air into water, water to air, and water in
water can be studied easily with the help of built-in laser, as a light
source, which revolves and can be fixed at any point around a circular
graduated scale. Includes leveling screws to level the water in the tank.
Circular scale has 6-3/8" diameter. |

| Ray
Box and Optics Set |
|
|
|
Use to perform experiments in
reflection, refraction, and color mixing. The box has hinged sides with
mirrors used for mixing of colors and rays of light. An adjustable lens in
the box is used to produce divergent, convergent, or parallel rays of
light. The light box has grooves to accept slit plates or color filters.
Comes complete with eight acrylic plastic blocks (one rectangular, one
semi-circular, one double concave, one equilateral 60 x 60 x 60 degrees,
two right angle 90 x 60 x 30 degrees and 90 x 45 x 45 degrees, one
circular, and one double convex), eight mounted color filters, two slit
plates, three mirrors (one plane mirror, one semi-circular, and one
parabolic), and one set of colored cards. Requires one 12V battery or 12V
power supply (not included. Spare bulb provided. Supplied in a thermocole
box with place for each part. |

Power Supply |
|
 |
3V, 4.5V, 6V,
7.5V, 9V, and 12V variable power supply. 12 volts and 2 amp transformer in
one source. 2A, switchable regulated. For use with Ray Box |
| Optical
Bench Set |
|
 |
Designed for basic geometric
optics experiments, including imaging by lenses and mirrors. The optical
elements are mounted in protective frames with mounting rods for easy
alignment, and the four captive riders have an index mark and set screws
to secure the rider and optical elements without disturbing their
alignment. The lightweight and precise parallel bar optical bench with
scale measures 37-3/4" x 4-3/4" x 4-3/4". Includes a
prefocused illuminator with a 12 V/6 W incandescent lamp, four 2"
dia. lenses, two mirrors, one object diaphragm, two screens, and manual.
Requires a 12 V/0.5 A power supply. |
| 24"
Light Pipe |
|
 |
Show the principles of fiber
optics. Direct a beam of light from a flashlight or a standard laboratory
light source into one end, and the other end will emit the light in a
superb display of internal reflection. Pipe is formed in a manner that
requires light to travel in a non-linear path in order to transverse from
one end to the other. Engineered of 1/2" clear acrylic. |
|
|
| Educational
Diffraction Gratings |
|
 |
Three diffraction gratings
mounted on the same slide 100, 300, and 600 lines per mm. Individual
gratings measure 1/2" x 3/8". Slide measures 3" x
1-1/4". |
| Linear
Polarized Film |
|
 |
Polarizing filters are used for
experiments involving birefringence, light scattering, polarized light
experiments, light reflection, Brewsters angle, and how polarized
sunglasses work. Slide mounted frames for easy handling. 10" x
17" sheet. |

| EMR
Chart Poster |
|
 |
A great chart for a difficult
subject. Shows all known ranges of EMR, including: gamma rays, X-rays,
ultraviolet light, visible light, infrared, microwaves, and radio waves
(ULF, VLF, LF, MF, HF, long, short, HAM, VHF, UHF, SHF, EHF, cosmic
microwave background radiation, and brain waves), all organized by
octaves. The audio frequency spectrum is also included. There are
descriptions for all ranges and properties of EMR: reflection, refraction,
LASER, television, gravity waves, emission, and absorption. Features a
chart of SI unit prefixes ranging from yocto to yotta. All items are
placed on the graph using custom-programmed formulas. 24" x 36"
laminated poster. |
