Abstract
An optical head includes a first module that concentrates pump light and Stokes light on a first point; a second module that collects CARS light from the first point; and a third module that supports the first module and the second module. The first module includes: a high rigidity first frame; and a first optical system including a plurality of optical elements fixed to the first frame. The second module includes: a high rigidity second frame; and a second optical system including a plurality of optical elements fixed to the second frame. The third module includes a high rigidity third frame that fixes the first frame and the second frame.
Claims18
An optical head comprising:
- an emission block that includes a high rigidity first frame and a first optical system including a plurality of optical elements fixed to the first frame to concentrate a plurality of light of different frequencies or frequency bands on a first point to obtain a nonlinear Raman effect;
- a collection block that includes a high rigidity second frame and a second optical system including a plurality of optical elements fixed to the second frame to collect light to be measured emitted from the first point;
- and
- a supporting block that includes a high rigidity third frame, the first frame and the second frame being fixed on the third frame to support the first optical system and the second optical system precisely positioned each other to the first point.
