Adjustable Analyzer Replacement

Add the Vernier Optics Expansion Kit to your Dynamics Cart and Track System to conduct optics experiments, such as image formation with lenses and light intensity vs. distance. You can even use the kit to build a basic telescope. The parts of the Optics Expansion Kit snap on to the track, so that the parts can be left in place while the track is moved. The three lenses are permanently mounted in three plastic supports. The light source is LED-based, so that it uses less energy and is cool to the touch. A rotating disc on the light source gives you the option of a radiant object, a point source, an “L” with 2 by 1 cm dimension, and parallel lines for resolution experiments. The power supply is the same as the LabQuest power supply. An additional aperture plate is included for experiments based on lens diameter and shape. For additive and subtractive color mixing experiments, check out the Color Mixer Kit. The Optics Expansion Kit requires a Vernier Track to serve as an optics bench. The Vernier Track is included with a Vernier Dynamics Cart and Track System.

The Polarizer/Analyzer Set extends the Optics Expansion Kit to allow students to study polarization of light. Using a Rotary Motion Sensor to record analyzer angle, Malus's Law experiments are easy, detailed, and accurate. The Polarizer/Analyzer Set includes a Fixed Polarizer, an Adjustable Analyzer, and an Adjustable Analyzer for Rotary Motion Sensor. Add to these the Light Source and Light Sensor Holder from the OEK, a Rotary Motion Sensor, and the Light Sensor for a complete system for studying polarization. The Fixed Polarizer linearly polarizes the light from the Light Source. The Adjustable Analyzer for Rotary Motion Sensor uses the Rotary Motion Sensor to record the angle of the analyzer. The Adjustable Analyzer can be placed after the Polarizer to study the curious behavior of stacks of three polarizers. A Light Sensor measures the transmitted light intensity, allowing a simple Malus’s Law activity. Polarizer passes vertically polarized light. Adjustable Analyzer for Rotary Motion Sensor includes a mount for the Vernier Rotary Motion Sensor to record the analyzer angle. Adjustable Analyzer includes an angle scale for manual reading of the polarizer angle.
