012–06348A Slit Accessory
Introduction
The PASCO OS-8529 Slit Accessory is designed for use with the
OS-8528 Diode Laser on the optics bench of the Introductory or
Advanced Optics Systems (OS-8500 or OS-9254A). The set of two
➤
disks has many different types of slits for diffraction and interference
experiments. The special comparison patterns have two different slits
spaced close enough together so they can both be illuminated by a single
laser beam at the same time, allowing students to compare the two
NOTE: Due to limitations of the
photographic process used to
produce the slit film, the line and slit
may not be exactly the same width.
