QRc: radius of curvature measurement system using a laser-based DMI

QRCThe QRc radius measurement system from QED Technologies is an optional feature that enables precise measurement of the radius of curvature using a laser displacement measuring interferometer (DMI). When combined with the QED metrology systems’s 820 mm Z axis stage, the QRc can provide robust radius measurements right on the the plant floor.  There is no longer a need to remount your optic on a separate linear scale system.  As you might expect from QED, we integrate the system directly into any QED metrology platform so it operates seamlessly with the QED.NET software. This means you can get precision radius of curvature measurements quickly, easily, and best of all, it happens automatically. The QRc is available for any QED metrology system using QED.NET software.

With QED’s QRc, you can get precision radius of curvature measurements, quickly, easily and best of all, it happens automatically.





Attenuation Filter: Increasing your metrology capabilities even further

AttenFilter packageQED introduces an easy-to-use attenuation filter designed for use with QED’s metrology systems.  By increasing the fringe contrast for high reflectivity parts, the QED Attenuation Filter improves your measurements, resulting in better data and better parts. Available in 4” and 6” options, the QED Attenuation Filter can also be used on other interferometers, in either vertical and horizontal orientation and it fits any Zygo transmission spheres or flats.

Design features make mounting easier and more reliable; operators can confidently mount the Attenuation Filter to their interferometer using a secure clamping system.  Thanks to QED’s design innovation, it’s easier than ever to exchange or replace pellicles.  The QED Attenuation Filter kit includes a pellicle holder, replaceable pellicle, magnetically mounted pellicle protection covers and a fixture to easily replace commercially purchased pellicles yourself, without damaging the pellicle.  This reduces long term costs and downtime waiting for vendors to replace pellicles in custom holders.  The QED Attenuation Filter comes in its own storage case to keep it protected when not in use.


 Product Features:

  • Low profile design: slim assembly maximizesthe interferometer measurement cavity.
  • Removable magnetic covers: attach securely to protect the pellicle and are very easy to install or remove.
  • Mounting ring included for easy installation of pellicles.
  • Engineered to be lightweight and easy to handle.
  • Durable case with handle: keeps the Attenuation Filter protected when not in use.
  • Ring style clamping system ensures full contact around transmission element:  stable and secure in both vertical and horizontal orientations.
  • Designed for easy lifting and carrying.
  • Spring loaded mounting pins allow easy and quick access to the pellicle for simple, tool-free changeovers.


The Stitching Advantage

Stitching technology has four major advantages over standard interferometry:

  1. larger field of view—you can see “more” of the surface
  2. higher lateral spatial frequencies—you can see a better picture of the surface
  3. improved accuracy—you can feel confident in the quality of your results because the unit automatically calibrates systematic instrument errors
  4. aspheric measurements—you can measure aspheres without null lenses

The "Q" Advantage

QED’s ASI(Q), is the latest innovation in precision optics metrology, brought to you by QED Technologies. The ASI(Q), completely designed, engineered and built by QED, is powered by QIS, the QED interferometer for stitching. Optimized for stitching, QIS enables you to measure more parts, measure them better, and say yes to more complex projects. QED innovation and ingenuity inside, brings expanded capabilities and new versatility to the ASI(Q). QIS is available on the new ASI(Q) platform, or as a field upgrade to existing ASI and SSI-A platforms.
