Handheld Microscope Users Guide

Which model do you have?
There are several types of hand-held microscopes, some of which are sold as toys. This manual
provides detailed instructions for four models designed for classroom use: the “New” Scope-On-
A-Rope (VL-7EX II), the “Old” Scope-On-A-Rope (VL-7EX), the L2, and the ProScope. The chart
below will help you distinguish these different models.
The name Scope-On-A-Rope is trademarked to Louisiana State University and is used to denote
the model used by its outreach program. Although there are several models of hand-held scopes
available, the outreach program at Louisiana State University recommends the Scalar VL-7EX II
(aka the “New” SOAR), which was introduced in the Fall of 2008. It is the most durable, has the
highest resolution, and is the most versatile of all the hand-held scopes currently available. The
original VL-7EX SOAR (aka the “Old” SOAR) was first sold in 1998. These two versions of the
scope are virtually identical, and both have superior resolution and durability.
