    Vertical Benchtop Optical Comparators

    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).

    Graphic Display Screen

    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.

    Mitutoyo Linear Height Gauges

    Image of Product. Front orientation. Contains Inset. Height Gauges. Mitutoyo Linear Height Gauges.
    Measure diameters, angles, and other complex geometries—like an optical comparator—but without all the training. These gauges have an easy-to-use touch screen that guides you through taking measurements step-by-step. Extremely precise, they measure in the smallest increments of any height gauge in our offering, and they’re also our most accurate. Use them in machining and toolmaking to mark material before cutting it. To fly through big batches of work, program up to 50 types of repeated measurements.
    From calibration reminders to calculation error alarms, these gauges have functions to make sure they give you accurate and consistent readings. Upon startup, they walk you through a scale check to detect traces of contamination that would cause errors. The air bearing system helps the slider glide smoothly up and down yet holds its spot steady when it’s time to measure. Rotate the screen to read it at the angle you need. Zero-position memory, also known as absolute (ABS) positioning, retains the measuring position even when the gauge is turned off.
    With up to two months of storage to record actions and measurements, these gauges create an archive you can look through and identify trends. Connect them via Bluetooth to your phone, tablet, or other devices to remotely monitor and analyze data in real time. Otherwise, use the SPC data output to connect to a computer or data processor. To send data right into programs such as Excel, use a USB cord or RS-232 cable (both not included).

    Let in maximum light to view details with greater clarity than traditional loupes. First designed for jewelers, these loupes also work well for quality control and inspection.
    Add a scale to 7X loupes to measure as you magnify.
    Plastic Lens—Loupes with a plastic lens are more lightweight and shatterproof than those with a glass lens.
    Glass Lens—Loupes with a glass lens are less prone to scratches than those with a plastic lens, so they provide a clearer view over time.
