United Scientific affordable medium plastic prism makes delight your students as they use this prism to separate white light into a spectrum of color. Warning: Chocking Hazard - Small Parts. Not for children under 3 years.
Diffraction Grating Slides - Double Axis 13,500 line/in. Our Holographic Diffraction Gratings are highly efficient embossed Holographic Optical Elements (H.O.E.). Diffraction Gratings are used for the direct viewing and analysis of spectra from different gas tubes and other light sources. The quality of the spectrum produced from our gratings is the brightest possible with a minimum of distracting visual noise. Our gratings are the principal component in a spectroscope and are used for experiments pertaining to the study of light and color. Project a spectrum using an overhead projector or 35mm slide projector for spectrum demonstration purposes. Use in conjunction with colored film gels for additive and subtractive color demonstrations. 2" X 2".
American Educational Concave Parabolic Large Demonstration Mirror, 40.5cm Diameter, 68cm Focal Length
Manufacturer: American Educational
Brand: American Educational Products
The American Educational Concave Parabolic Large Demonstration Mirror is a large-diameter mirror for demonstrating optical principles and effects for students. This mirror is concave and parabolic to generate both real and virtual images from real objects. The parabolic shape focuses parallel rays to a single point. The mirror has a 68cm focal length and is 40.5cm (16") in diameter. Mirrors are used in scientific experiments and classroom demonstrations to explore optical principles such as reflections and refraction. Science education products incorporate applied math and science principles into classroom and homeschool-based projects. Teachers in pre-K, elementary, and secondary classrooms use science education kits and products alongside science, technology, engineering, and math (STEM) curriculum to demonstrate STEM concepts and real-world applications through hands-on activities. Science education projects include a broad range of activities, such as practical experiments in engineering, aeronautics, robotics, energy, chemistry, physics, biology, and geology. American Educational Products manufactures learning materials in math, science, and reading/language arts for students in pre-kindergarten through grade 12, under the Scott Resources, Hubbard Scientific, National Teaching Aids, and Ginsberg Scientific brands. The company, founded in 1986, is headquartered in Fort Collins, CO.
Eisco Labs Light Box - 27 Piece Optical Kit, Covering 18 Topics in Optics with Full Activity Guide
This kit is very useful for reflection, refraction, and color mixing experiments. The light box consists of a light source 12 V, 24 W lamp, producing convergent, divergent or parallel beam. On one end, an adjustable cylindrical convex lens (for parallel beam) and on the other end, a triple aperture system for color mixing experiments (lateral aperture are provided with adjustable hinged mirror). All apertures in the box are provided with vertical channels to hold slit plates and color filters. The optical set includes acrylic blocks, set of three mirrors, 2 slit black plates, one with three narrow slits at one end and one narrow slit at the other end. Another black plate with four narrow slits at one end, one wide slit at the other end and set of seven mounted color filters. Supplied with working instructions. Kit does NOT includes power supply, must be purchased separtely.
