Carry-along microscopes for gear manufacturing applications are more sophisticated than their convenient size may suggest. The latest models of these precision optical instruments offer magnification up to 50x, sharp resolution, measurement capability and built-in illumination.
The professional-grade tools are both durable and portable, making them useful for quality control inspection of incoming parts, prototypes and assembly samples.
Five pocket-size microscopes are featured by Aven, Inc., a global distributor of optical inspection equipment and high-performance tools. Four provide internal light for bright, clear examination of small objects and areas by engineers, tool makers and quality inspectors. A clear acrylic base lets ambient light reach examined objects.
A flip-open illuminated model with an angled viewing tube has 40x magnification and a measuring range up to 4 mm. Three other battery-operated illuminated pocket scopes with 20x, 30x and 50x magnification are from Carton Optical Industries, which also manufactures full-size microscopes, binoculars, telescopes and ophthalmic instruments.
The product line includes a pen-size 25x scope with pocket clip and a metric measurement glass reticle. A beveled clear base opening gathers and focuses ambient light.
Each instrument is powerful enough to detect hairline cracks, assembly flaws and other imperfections.
