Basic Optics Aperture Bracket

The Aperture Bracket acts as a mask for a light sensor.  Rotate the wheel to select different sized slits, which determines the spatial resolution.  Use narrow slits to scan diffraction patterns with fine detail. Use wider slits to scan patterns from dimmer sources.  Use the diffuser selection for inverse square law experiments.

This bracket accommodates either a PASPORT or a ScienceWorkshop Light Sensor (not included).
