Optical probe of spectroradiometer
An optical probe has a connecting part, a carrier, multiple optical fibers, and a lens hood. The carrier is inserted in the connecting part. The carrier has two opposite ends and a channel. The channel extends to the two opposite ends of the carrier. The multiple optical fibers are inserted in the channel of the carrier. The lens hood is connected to the connecting part. The multiple optic fibers inserted inside the channel are able to cover various orientations of oscillations of polarized light, promote accuracy of inspection result, and save a lot of time from repeated measuring.
