Laser Pointer
A handy, low-cost, pen-sized laser pointer for many applications
— education, scientific research, or everyday life!
By simply pressing the laser pointer’s pen clip, a laser
beam is activated. Comes with an instruction manual
which contains optics experiments. Lifetime warranty. Sh.
wt. 0.17 kgs.
SB23600M — $23.75
Laser Pointer
Key Chain
This 2½"-long laser
pointer comes with a key
chain for added convenience.

wt. 0.25 lbs.
SB47407M — $2.10
Laser Pointer
Sturdy construction and long battery life allow for heavy
use as a teaching tool for scientific presentations, conferences,
lectures, seminars, and planetariums. The attractive
metal pen-shaped unit can be easily carried in a shirt
pocket. Projects a brilliant red dot clearly visible even in
bright ambient light or with video, film, and slide presentations.
Runs for a minimum of 4 hours continuous
use on two standard alkaline batteries (included). Sh. wt.
0.23 kgs.
SB29122M — $56.85
Green Laser Pointer
An economical green diode laser pointer with a 1 mW
power output (class II) and a 532 nm wavelength. Green
laser light appears much brighter than red light of the
same power because of the greatly increased sensitivity
of the eye to green light compared with the longer
red wavelengths. This makes a green laser pointer ideal
for optical experiments, as well as offering an additional
wavelength of light for diffraction and interference
experiments. Operates on two “AAA” batteries. Comes with
attractive storage case. Grade 6 and up. Sh. wt. 0.50 lbs.
SB43423M — $41.65
Violet Laser Pointer
Use for far more than just pointing! The
stunning blue-purple glow can be used for
spectroscopy, fluorescence, microscopy, and more.
The 405 NM wavelength beam has a power output of
greater than 5 mW. Beam dimensions are 1 mm at aperture.
Operating lifetime is 1,000 hours. Requires 2 “AAA”
batteries (included). Sh. wt. 1.50 lbs.
SB48473M— $34.50
Refraction Cells
These clear acrylic refraction cells are excellent for showing
refraction and internal reflection in water, and to
measure its refractive index. The cells have uniform wall
thickness to eliminate distortions. Grade 7 and up.
Refraction Cell Set. Includes one of
each cell listed below. Sh. wt. 0.38 lbs.
SB48379M— Spectrum Price
$10.15
Semicircular Refraction Cell. Sh. wt. 0.25 lbs.
SB48377M— $5.90
Rectangular Refraction Cell. Sh. wt. 0.25 lbs.
SB48378M— $5.90
Hartl Optical Disk
Designed to demonstrate
laws of reflection and
refraction in optics. The
set consists of an 11"
rotatable disk with a 360°
graduated scale, a light
shield, a heavy tripod
stand, and activity guide.
Accessory kit includes one each of plane mirror, convex
lens, concave lens, prism, trapezoid, and semicircular
lens. All items in accessory kit are made of optical glass.
Requires a light source (not included). Grades 7-12. Sh.
wt. 4.50 lbs.
SB49330M — $233.15
Educational
Diffraction Gratings
Three diffraction gratings
mounted on the same slide
100, 300, and 600 lines per mm. Individual gratings
measure ½" x 3 ⁄8". Slide measures 3" x 1¼". Sh. wt. 0.50 lbs.
SB45751M — $26.80
Flashlight
Set
Set of two 6"
long flashlights
to fit in pocket,
briefcase, purse,
etc. Complete
with wrist band.
Requires two
“AA” batteries
(not included).
Sh. wt. 0.09 kgs.
SB31462M —
$4.20
Geometrical
Optical
Experiment
Instrument
Ideal for introducing
students to the
concepts of reflection
and refraction.
The movable arm
carrying the laser
light source is
parallel to the protractor
disk, allowing
students to
carefully measure
the reflection and refraction angles, internal reflection,
and refraction index. Circular water tank measure 4¾"
dia. The protractor disk and laser light attachment can be
removed from the water tank and can be used for separate
experiments. Equipped with two mirrors that combine
plane, concave and convex, semi-circular, bi-convex,
and plano-concave lenses. Sh. wt. 1.75 lbs.
SB47768M — $100.60

Physical Science
Nature of Light & Colour
Light: The Visible
Spectrum Lab
This lab explores the spectrum of colors
that makes up white light. Students use diffraction gratings,
then build a spectroscope to investigate the spectra
of different light sources. They gather evidence showing
that different light sources have different spectra and
that colored filters absorb some of the colors in the
spectrum. Includes light station; set of four colored paper
strips; set of eight colored pencils; fluorescent light bulb
with socket, cord, and slotted shield; red, green, and blue
filter slides; square-frame diffraction grating; four round
diffraction gratings; single-slot and diffusing masks; two
spectroscopes with tubes and endcaps; two color transparencies;
two mirror/slide holders; five student guides;
and teacher’s guide. Grades 6-12.
Sh. wt. 3.50 lbs.
SB48323M— $178.50
Light: Refraction and Lenses
Explore how lenses change the direction
of light through the process of
refraction and can produce images. Using both convex
and concave lenses, students compare magnification,
measure focal length, and figure out how to construct
a simple camera. Includes light station; round, oval, and
flat-sided (rectangular) bottles; large round positive glass
lens (2"); small round positive glass lens (1"); two positive
rectangular Fresnel lenses; negative rectangular Fresnel
lens; glass lens holder and base; T-shaped beam blocker;
translucent screen; mirror holder; object mask; camera
box; single-slot and three-slot masks; diffusing mask;
1-1⁄2 m tape; viewing screen; two viewing screen stands;
four white cards; and teacher’s guide. Grades 6-12.
