The R/S Plus series is now available with enhanced encoder for increased measuring and control capabilities while maintaining sophisticated rheological analysis - all at an affordable price.

The R/S Plus is available in three configurations: Model R/S-CC (coaxial cylinder), Model R/S-CPS (cone and plate) and Model R/S-SST (soft solids tester with vane spindles) for a variety of samples.

All R/S Rheometers have a rugged design for many years of trouble-free operation. Rapid spindle attachment and easy to clean surfaces ensure its use will save you time and money.

R/S Plus Rheometers include such unique features as:

Wide torque range: 0.05 to 50mN.M

Variable speed from 0.01 to 1000 rpm

Stand-alone operation for quick single point evaluation or programmed tests using keypad

PC interface for powerful capability of flow curve analysis, determination of yield stress and thixotropy when running Rheo2000 software

Measurement of yield stress and strain, modulus and creep

Test method sequencing capability to assess complete flow behavior of sample including rebuild/recovery evaluation after shearing

Quality control mode enables tolerance bands to be placed around measurement data for immediate visual pass/fail determination

Brookfield's revolutionary YR-1 Rheometer gives you the ability to measure your materials Yield Value in a snap! Simply select a test, lower the vane spindle into the product, press GO, and the instrument displays the result in a single shear stress number.

The simple-to-use YR-1 is a low-cost alternative to complicated, full-featured laboratory rheometers. It can be used by your technicians right on the production floor for rapid QC testing with excellent repeatability. The YR-1 is ideal for materials ranging from low to high viscosity, everything from juice with pulp to shortening. Typical applications include: greases, screen printing inks, creams and icings, polymers, and select personal care products.

The YR-1 comes with EZ-Yield software which allows for simple data collection on a PC. EZ-Yield allows you to set up 10 different test programs with an easy-to-use test parameter menu which can be downloaded and stored in the YR-1. Streaming data can be viewed in EZ-Yield and test data (torque vs. time and stress vs. strain) is displayed in both tabular and graphical formats.

The YR-1 Rheometer also comes with two Vane Spindles (V-72 and V-73) and a carrying case. Several additional vane spindles are also available.

- Optics perfect to within λ/30!

Thanks to the development of innovative new surface finishing technologies, ELCAN Optical Technologies can now offer reflective optical surfaces with <30 nm PV accuracies & micro-roughness <0.5nm rms, perfect to within λ/30. This level of performance was developed for heavily-funded, small-quantity, mission critical defense & aerospace applications, but is now available as predictable, repeatable, cost-effective optics in optical glasses, mirrors, ceramics or single crystals for your medical 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 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.

Cost-Effective, Repeatable Technology

Until now, the only approaches available to optics manufacturers required skilled craftsmen, time-consuming manual operations, and dedicated tooling—resulting in long lead times and less predictable results.

The high, interferometrically characterized removal rates reduce cycle times, require less dedicated tooling and produce results an order of magnitude more accurate than DPT alone. Operator proficiency is reached in weeks – not months or years.

Within the magnetic fields the MR slurry provides a polishing pad that accurately conforms to complex shapes, thereby enabling precision polishing of aspheric and other non-standard surfaces. The same procedure is utilized for all substrate materials making MRF optical production ideally suited for both rapid prototyping and low-to-medium volume production runs.

Application of the technology

Estimates for cancers of the breast, colon, rectum and cervix alone, total premature mortality in 2003 to have been approximately 1.7 million years of life lost. Early detection and correct diagnosis are keys to improving these statistics.

Current cancer diagnosis is invasive, time-intensive, expensive, prone to sampling errors and delayed diagnosis. Overcoming these challenges will require development of tools to allow real-time, 3-dimensional, accurate results.

In order to accomplish this, medical device manufacturers are looking toward multi-spectral and/or multi-modal technologies that meet these time and cost requirements. These requirements put further pressure on the quality of the optics as well as the cost-effectiveness of the technologies used to produce them.

This revolutionary solution is seeking a challenging problem – and as it happens, ELCAN Optical Technologies will be there.
