Instructions for protecting the calibration target

The glass or ceramic substrate calibration targets are made with a high flatness and low thermal expansion coefficients. There is not much to maintain, but of course you should be careful using the target. Don’t let it fall down, be careful during transportation, the side showing the pattern should be upside during use and transportation. Avoid scratches.

If you notice dust on the calibration target, use ear washing bulbs to remove the dust. If there’s dirt on the target, use clean water and woven cloth to clean it.

Holes/ angles/ corners on the calibration target are available

Irregular shapes of calibration target are available
