Don't let their small size fool you, these are precision made hand crafted inspection tools! Some times called "pocket microscopes" they are also referred to as "microscope pens" or "pen microscopes". This fine optical instrument is heavy duty and will for years.
Each of these precision crafted microscopes provide high resolving power and a surprising amount of brightness in the final image. The PEAK pocket microscope is used whenever someone is confronted with the need to see something better than they could otherwise see with the unaided (or naked) eye. It comes with a pen clip to conveniently clip right onto a shirt pocket, just as you would a ball point pen!
To focus the microscope, hold it so that the notch at the tip of the acrylic cylinder faces toward the user. While tilting back and forth on the tip, with your eye looking through the eye piece, you can fix the adjustable cylinder until all is in focus to give the sharpest image. The microscope comes in four different magnifications. Many of our customers purchase more than one, with different magnifications.
