TRANSCRIPT
Future of Spectroscopy and Imaging System
We provide high-performance tunable diode lasers,
which open up new era of spectroscopy and imaging.
Advanced Tunable Diode Laser
Spectra Quest Lab, Inc.
Spectra Quest Lab was founded in 2013,
Chiba-University Inohana Innovation Plaza,
based on the heritage of JST Sentan Project
āHigh Power and Widely Tunable Diode laserā.
Our products are based on āpatented design
of laser cavityā and āhigh-power gain chipsā,
which were specially developed for tunable
diode laser by OPTOENERGY, Inc.
