Kiʻekiʻe-Throughput Transmission Fiber Spectrometer

Hoʻohana ka JINSP kiʻekiʻe-throughput transmission-type fiber optic spectrometer i kahi VPHka nui holographic grating me ka diffraction pono ~90%.Hoʻopili ʻia me kahii hoʻolālā maikaʻi ʻia ke ala optical no ka hana kiʻi, hiki i kona ʻike ke piʻi i ʻelima mau manawa o ka spectrometer reflective.Me ka hoʻonā ʻana ʻelua ʻoi aku ka kiʻekiʻe ma mua o nā spectrometers maʻamau, hāʻawi ia i nā hopena maikaʻi loa no ka ʻike spectral.Eia hou, ʻo ialako me kahi kāmeʻa CCD kāmeʻa noiʻi hohonu hoʻoluʻu wahi hoʻoluʻu, he kiʻekiʻe ka quantum pono a me ka lākiō hōʻailona-a-noise.Eia kekahi, ua hōʻike ʻia e ke kūpaʻa kiʻekiʻe a me ka nui compact, i kūpono no ka hoʻohui ʻana i nā mea hana ʻoihana.
Ma waena o lākou, hiki i ka ST50S ke pani a ʻoi aku ma mua o ka pae noiʻi kuʻunaInGaAs spectrometers.He koho maikaʻi loa ia no 1064 nm Raman spectroscopyʻōnaehana ʻike me nā koi sensitivity kiʻekiʻe.
He kūpono ka ST90S no nā ʻōnaehana ʻike kikoʻī Raman laser 532 nm, ʻoi aku ka nui o ka ʻike hōʻailona Raman.Loaʻa iā ia nā hiʻohiʻona optical ākea ākea, kahi ākea ākea a hiki i 4200 cm^{_{- 1}}.a me ka hoʻonā a hiki i 4cm^{_{- 1}}Hiki iā ia ke hoʻololi i ka largem, lawe ʻia mai, ka noiʻi-grade reflective spectrometers.
Hiki ke hoʻohui ʻia ka ST100S i loko o nā ʻōnaehana Raman laser grade 785 nm no ka ʻike spectroscopy o Raman.a me nā laʻana olaola, me ka hoʻonā i lalo i 3cm^{- 1} .
