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.

Measure and inspect precise features by projecting a magnified shadow or image of your part onto a screen. These optical comparators 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. From o-rings to castings, they work to inspect parts with simple or complex geometries. They shine light from the side, so unlike vertical comparators, your part can be held from underneath for stability. 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 parts 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.

These comparators come with a variety of features to streamline your inspection process. For a quick way to compare manufactured parts to designs, set desired dimension and tolerance limits. You can also create a program that guides anyone using the comparator on what steps to follow, so each part is inspected the same way. To save everything for later, print the data or export it as a spreadsheet or text file to a computer with a USB or RS-232 connection.

Changing the magnification is as easy as twisting the current lens until it pops out and twisting in a new lens (sold separately).

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.

Rotary vises (sold separately) give you a secure way to hold up and rotate objects.

Cabinets (sold separately) can serve as a stand for your comparator and as storage for lenses and other accessories.
