Measure multiple surface* cavities as thin as 0.075mm
Confident accuracy with no back reflections, unique real-time visual feedback, and fast electronic fringe positioning via ÄPRE patented SCI technology
*Substrates, prisms, wafers, masks, domes, display glass, disks, boules
Back Reflections: Does your light source limit you?
Laser: Paint/Tape
Damaged surfaces
Time Wasting
Warps thin parts
Consumables $
Wavelength Shifting: SLOW
>1 minute acquisitions
~0.5 mm thin limit
No visual feedback
Slow=Poor repeatability
SLED/White Light: Limited
0.3 mm thin limit
Very hard to align
Limited capture range
Manual fringe positioning
SpectrÄ: Fast, accurate, easy-to-use & cost effective
