One-Button Calibration for your digital microscope

Caliwedge target with one button calibration software

Easily calibrate your ZDM or other digital microscopes for accurate measurement at any magnification.

Determine lens magnification, telecentricity, distortion, field curvature, depth of field and more.


The CaliWedge (Patent Pending No. 15/062,663) is the new and easy way to use the included Wedge Reader PC software for one-button calibration on your MiScope and MiScope Megapixel 2.

Calibration, magnification, telecentricity, distortion, field curvature, depth of field and more are easily obtained. With the included advanced interferometry techniques in the Wedge Reader PC software you will get an accurate calibration that is compensated for lens distortion.

First place the object you want to measure under your ZDM or other microscope and focus it using the focus block. Then, place your CaliWedge under your lens, and move it until it is in focus on the center of the CaliWedge lines (without moving the focus again). Then click the wedge button in your Wedge Reader software and your ZDM or other microscope is now calibrated. Now use your ZDM software for measurements of the object you previously focused on using your Video Toolbox PRO or Premier PC software and it is calibrated for accurate measurement. If you are using another microscope and don't have Video Toolbox PRO or Premier software, you can enter the calibration into your microscope's measurement software.


Need to see the exact magnification of your lens? It is listed on your page after your one-button calibration.


Need to generate a report for documentation? It's easily done by clicking the report button which is then ready to sign and file. Includes telecentricity, distortion, field curvature, magnification, depth of field and more.


Need to test your lens properties or set zoom lenses for their optimal imaging conditions? The CaliWedge can do that with one-button calibration.
