摘要 |
<p>Disclosed herein is a reflected light measuring instrument for receiving reflected light from an object under measurement, which has an effect that even if a reflection surface of the object under measurement shifts in position in the direction of an optical axis, a quantity of reflected light at the reflection surface is automatically corrected to be substantially constant, whereby the read accuracy on said reflection surface is not lowered at all.</p> |
