Decreases parasitism reflection the optical challenge device and removes parasitism reflection the mannered

摘要

Diffraction grating coupling with a surface having a sensing region that can be an optical device for detecting biological agents, chemical agents or biochemical preparations, immobilized 1) biological materials, chemicals or biochemicals and an optical detection device for monitoring an optical sensor with a waveguide, the sensing region of 2) above, the apparatus described above, an optical isolator to eliminate the parasitic reflections generated by the optical sensor of the above I further comprises a.
