When returning equipment for repair, the units must be packed properly. Carriers will not accept responsibility for damage caused by improper packing. To be certain the unit will not be damaged in shipment, observe the following rules:
The shipping carton must be strong enough for the
item shipped.
Make certain there are at least two inches of packing
material between any point on the apparatus and the inside walls of the carton.
Make certain that the packing material can not shift in
the box, or become compressed, thus letting the instrument come in contact with the edge of the shipping carton.

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.
