Slink, Wave Demo (1813)
Wave Demonstration Spring
Studying waves in physics class can sometimes be difficult for students to conceptualize. This 3" diameter flat spring steel apparatus can make visualizing wave propagation much easier. The plated spring can be stretched across the room allowing the entire class to witness the wave traveling back and forth. (3" x 3" x3"; 1Ib).

Intermediate Spectrometer, Model JJY-1' (1925)
Advanced Spectrometer Designed for easy set-up and use. This spectrometer's sturdy iron base incorporates a 20cm-diameter divided table with highly visible etched graduations and a vernier scale that can be read to a resolution of 1 minute of arc. The revolving 7cm-diameter prism support rotates 360 degrees and has a height adjustment of 2cm, thereby accommodating a wide range of test conditions. A built-in illuminated auto collimator eliminates the difficulty of telescope-collimator alignment. Accessories include an illuminated magnifier, glass diffraction grating and holder, auto collimation mirror, power adapter, brush, screwdrivers, extra bulbs, and instruction manual.

Basic Spectrometer (1928)
Basic Spectrometer Great for high school laboratories - a perfect device for any intermediate-level classroom! Built from sturdy metal, this unit includes an adjustable collimator tube, telescope, and prism stand. It provides a high quality optical system and an easy to read etched scale, which allows the student to measure spectrum lines with a resolution of 50A. Light is directed in the collimator tube and focused to the adjustable telescope, which has a scale inside to allow special lines to be reliably measured. Includes a 600-line millimeter diffraction grating, grating holder, 3x2.5cm equilateral glass prism, prism hood, which helps block stray light from entering the spectrometer.
