CScope USB microscope

Regular price $349.00 CAD

 NEW: Now includes an extra long zoom extension and a lens locking ring which allows you to fix the lens at any zoom setting.

USB Centering scope / Touchless Probe / Optical Edge Finder for use on manual or CNC milling machines. Can be used for accurate part location as well as precision measurement.  Ideal for non-contact digitizing. Includes a zoom extension and lens locking ring for resolution down to 0.0001inch (0.0025mm).  Works with included Windows CScope software, Mach3 or Tormach "PathPilot" (not included).  Also compatible with all UVC compliant software.

Comes in 2 Shaft Options:

  • 3/4 inch hardened steel shaft fits directly into 3/4 collet.  This is ideal for larger milling machines.
  • 10mm Stainless steel shaft.  Ideal for when you prefer to use your own tool holder.

  • Low ambient light sensitivity allows working in poorly lit areas.  A large lens coupled with a low light sensor eliminates the need for illumination LEDs which cause glare.
  • Large working distance keeps the scope far away from the part being measured, greatly reducing the risk of crashes.
  • Calibration is done using the included CScope Software.  Third-party software can be calibrated using Calibration screws.  This allows the scope to be calibrated concentric to the spindle for use as an optical edge-finder or Centering Scope.
  • The extremely solid aluminum body provides a rigid mount without flex for accurate repeatability.

New Calibration Procedure!

The new CScope software version 1.3.2 introduced cursor calibration to greatly simplify the calibration procedure.  Not only is it easier, but it is also much more accurate!  This is the new calibration procedure:

  1. Install the CScope on the spindle with the USB cable facing away from you.  (In the Y+ direction)
  2. In the CScope Software press the calibrate button and set the X and Y offset to zero.
  3. Focus the CScope on a piece of rough metal and find a small round imperfection to center on.  The smaller the better.  This will become your "reference dot".
  4. Center the machine on this dot.  Zero the X and Y DRO on your mill.
  5. Rotate the CScope 180 Degrees in the spindle.  The USB cable should now be pointing towards you.
  6. Re-Centre the scope on your reference point. 
  7. Read your DRO X and Y values and set them to half the current reading.  ( /2 on some machines)
  8. Move the machine to read 0 0 on the X and Y.  (CNC users: G0 X0 Y0)
  9. In the CScope software Click the calibrate button and use the arrow keys to move the cursor to the center of your reference dot. 

To verify if you are properly calibrated, rotate the CScope in the spindle.  The intersection of the cursors should rotate centered on your reference dot.

Tip for CNC Users:

With the CScope focused and Z axis calibrated, enter the tool height in your offset table.  This allows for fast and accurate focus using G0 Z0. (remember to set the tool number first!)
