OPTICAL MEASURING DEVICE AND SAFETY DEVICE USED THEREIN
First Claim
1. An optical measuring device comprising:
- a sample placement portion for a measurement sample to be placed therein;
a light source portion for emitting a measurement beam toward a measurement sample that is placed in the sample placement portion; and
a detector for detecting sample information from a measurement sample placed in the sample placement portion, wherein;
a cover portion that can be opened and closed in order to access the interior of the sample placement portion is formed in the sample placement portion;
comprising;
an optical element member for not transmitting light of at least a prescribed wavelength band within the measurement beam; and
a driving mechanism for linking mechanically to the opening and closing of the cover portion, to move the optical element member, wherein;
the driving mechanism places the optical element member into the light path from the light source portion to the measurement sample when the cover portion is opened and places the optical element member outside of the light path from the light source portion to the measurement sample when the cover portion is closed.
