Magnify and measure in one operation.

5X and 10X glass-lens magnifying glasses have an eyepiece with scales on two sides; both scales are graduated by 1/32" and 0.5 mm.

10X plastic-lens magnifying glass comes with a detachable scale on the eyepiece that's graduated by 1/64" and 0.5 mm. The lens has a scratch-resistant coating.

View a clear image from edge to edge, even in dimly lit areas. These magnifying glasses have a curvature that corrects for distortion, so you can check objects for proper shape and size. Their built-in LED light emits a focused, even beam, making it easier to see details. You can turn the light on to illuminate parts and off to reduce glare on reflective surfaces. Take them with you to inspect equipment that’s running or to spot fine details on parts. Made of plastic, they’re shatterproof and lighter in weight than glass lenses.

Magnify and measure in one operation. The lens is mounted into a stand to keep it at the optimal distance for focused, hands-free magnification. Use both hands to inspect objects, repair parts, or record your findings. Also known as linen testers, these magnifiers are often used for quality control and thread counting in fabric inspection. Fold the magnifier so it's easier to move around.

Glass lenses are less prone to scratches for a clearer view than plastic lenses.

Clip these magnifiers onto the frame of your eyeglasses for viewing fine details— they flip out of the way when not in use.

By projecting a magnified shadow or image of your part onto a screen, these optical comparators give you an easy way to measure and inspect its precise features. They work similarly to overhead projectors, but with fixed magnification to preserve proportions. Because of how easy they are to set up and use, they’re a staple in most machine shops. They shine light from above, so they’re best for inspecting flat parts, such as gaskets and O-rings. Unlike traditional optical comparators, these comparators are compact to fit easily on a benchtop.

To use these comparators, choose profile or surface lighting. Profile lighting creates a shadow of your part, which you can use to plot points for precise measurements. To plot each point, move the stage the part rests on until the point lines up with the crosshair on the projector screen. For precision, the stage moves in increments thinner than a sheet of paper. Surface lighting makes these comparators work like an illuminated magnifier, blanketing the part with even light to reveal scratches, dents, and other surface flaws.

Save the measurements you’ve gathered for later by exporting the data as a text file using an RS-232 cord (not included).

Optical comparators with edge detection increase accuracy and efficiency by reducing human error. No need to identify each edge yourself with the crosshair—these comparators register whether they are passing over your object's shadow or a gap, such as a hole or cutout. The graphic display screen shows a visual representation of the part you’re measuring, making it easy to identify and measure specific features. To make sure each part is inspected the same way, create a program that guides anyone using the comparator on what steps to follow.

Holders, swivel center supports, and V-blocks securely hold your part as you measure. V-blocks hold round parts.

If you need to inspect your part from different angles, use either a swivel center support or a rotary table. Swivel center supports turn around a horizontal axis, moving your part in a circle like a Ferris wheel. Rotary tables spin around a vertical axis, rotating your part just like a carousel.

Scales and charts are clear, so you can lay them on top of your comparator’s projector screen. Scales give you a way to check your comparator’s magnification and length measurements. Charts are for checking angle measurements.

Filters are blue to increase contrast and reduce glare on your comparator’s projector screen.
