Thanks to the development of innovative new surface finishing technologies, ELCAN Optical Technologies can now offer reflective optical surfaces. Our reflective optical surfaces with <30nm PV accuracies & micro-roughness <0.5nm rms are perfect to within λ/30. Our reflective optical surfaces provide a level of performance that was developed for heavily-funded, small-quantity, mission critical defense & aerospace applications. Now we can offer our reflective optical surfaces as predictable, repeatable, cost-effective optics in optical glasses, mirrors, ceramics or single crystals for your medical applications in medical device manufacturing, medical imaging, and medical equipment applications - founded on solutions by ELCAN.

ELCAN's Pioneering Legacy
True to its pioneering legacy, ELCAN Optical Technologies has combined patented and proprietary technologies to create Tri-Technology Multi-Spectral Finishing - TriTec MSF to enable our partners in medical device manufacturing, medical imaging, and medical equipment applications to realize their concepts.

One element of this revolutionary process is Magnetorheological Finishing (MRF), a revolutionary technology patented by QED Technologies of Rochester, New York.

MRF is a computer-controlled precision surface finishing technology. This patented technology utilizes an interferometrically controlled MR finishing slurry (a suspension of micrometer-sized magnetic particles in carrier field), which becomes the precisely controlled polishing tool.

A thin ribbon of the MRF fluid is drawn onto a rotating wheel. An electromagnet below the wheel causes the fluid to stiffen in milliseconds. The fluid returns to original viscosity as it leaves this magnetic field. Shear stress created by "squeezing" the optical surface against the fluid creates polishing pressure over the optical surface. The MR fluid conforms to the local curvature of the optic.

A computer-driven algorithm generates an interferometrically characterized removal map and calculates the dwell time and position in order to accomplish the deterministic removal. Time, temperature and flow are regulated. The polishing tool never dulls or changes allowing the utmost accuracy. The extreme accuracy and computer-controlled stability of MRF (Magnetorheological Finishing) makes the fabrication and polishing of exceptionally precise spherical, aspheric and non-traditional freeform optical shapes possible.
