POG offers stage micrometers and custom microstructures made on different glass ceramics:

CERAN® and ROBAX® feature, like ZERODUR®, a high mechanical stability and a thermal expansion of virtually zero.
The engraved serial number and the optional available official DKD certification make it a perfect calibrated measurement equipment.

Due to the high contrast of the high reflective chrome structures on the dark CERAN® background these stage micrometers are in particular suitable for applications in reflected light.

ROBAX® has virtually similar specifications but a higher transmission in the visible range and is therefore applicable for throughlight applications.

Three different versions – 1mm in 100 divisions, 2mm in 200 divisions & 70mm with 4 different divisions (see picture) especially designed for stereo microscopes are standard products available from stock.

Further specifications and details can be found here.

DKD calibration possible.

Other microstructures – scales, calibration targets -on glass ceramics substrates in different dimensions can be designed and produced according to individual specifications.

Please contact us in case of any questions or requests.

Advantages

• scattering, matt finished surface with no direct reflection and reduced edge roughness compared to other ceramics
   or
• polished surface with feature sizes and edge roughness as on glass substrates
• high mechanical and thermal stability
• thermal expansion of virtually zero
• dense and pore free surface – easy to clean
• very good surface flatness possible
• substantial cost reduction compared to other glass ceramics like ZERODUR®

Applications

• 2D Calibration
• Reference Marking
• Photogrammetry
