Position Sensor measures short-range displacement.
With 3 mm standoff and minimal sensitivity to EMI, electro-optic NanoGage(TM) Model 100 offers linear measurement range of 100 microns and signal capture range of Ã-
Read More »Grid Encoder features contamination-resistant design.
Suited for use with NanoGridÃ-® system, contamination-resistant grid encoder allows for operation of position measurement systems in less than clean room environments. All grid elements are electrically connected, enabling entire grid surface to be set at fixed electrical potential to eliminate static electricity as well as inhibit particle accumulation. Product offers 3 user-selectable...
Read More »Arrays suit open-path, optical monitoring applications.
Plastic Injection-Molded Retroreflector Arrays are molded in 100 mm modular cells, which are assembled into larger arrays. They are intended for use with open-path Fourier transform infrared spectrometers.

Encoder Products utilize laser interferometry.
NanoGrid Model A has electronic interpolation to 0.3 Nm on ISA-bus compatible PC board with either 32-bit digital position word or optional A-quad-B format output. It delivers repeatability of better than Ã-
