An old but unscathed slide, and in perfectly useful condition:Planotec Silicon Calibration Specimen - 10µm PitchFrom the Ted Pella Web Site:
Single crystal silicon, 5mm x 5mm. The squares repeat every 10µm (0.01mm). The dividing lines are about 1.9µm wide, formed by electron beam lithography. A broader marking line is written every 500µm (0.5mm) which is useful for light microscopy. Lines are etched, and approximately 300nm deep. Available unmounted or mounted on SEM specimen mounts.
The reflective/graduated surface appears in perfect condition. That said, the blackened slide upon which it is mounted appears faded and greyed.
This box is oldenough that the foam supports have begun to deteriorate… and have been replaced. Discoveries from a decommissioned lab.
Still a perfect marker for Light Microscope calibration, either for scale or for image flatness. Lists new at $461.90. Yours for $199 plus shipping. More items to come…
