This piece functions by using two objectives to capture, and then superimpose two separate images, one of the original mask and one of the working mask. The ability to then measure and compare both images is enhanced by the following system features:
- One-touch changeover switch for coarse and fine movement of the large stage
- Excellent image resolution owing to bright illumination and top-quality Nikon optics.
- Observation wavelengths of 546.1 and 632.8 nanometers
- Digital display of image position and movement
- 200X, 400X, and 800X magnification (with 1.05mm, 0.25mm, and 0.28mm FOVs)
- +/- 0.1mm focusing adjustment range and +/-2.5 deg. rotation adjustment range
- Ability to produce 3.25" x 4.25" Polaroids of up to 400X magnification
