Princeton Instruments, which joined forces several years ago with Acton Research — an elite designer and manufacturer of renowned monochromators and spectrographs as well as high-precision optical coatings — is the world's leading designer and manufacturer of high-performance light-detection systems for spectroscopy, imaging, and x-ray applications. PI has defined the state of the art in CCD, EMCCD, ICCD, emICCD, and InGaAs camera technologies since the early 1980s.
Key innovations from Princeton Instruments have included the industry’s first spectroscopy camera to feature a photodiode array, the first spectroscopy camera to use a CCD, and the first high-performance gated, intensified CCD camera.
In addition to breaking new ground in the field of spectroscopy over the years, we have designed CCD cameras with the highest sensitivity available for scientific imaging applications (~2 e- rms read noise with >90% quantum efficiency). For high-speed, low-light applications, we offer unrivaled EMCCD, ICCD, and emICCD camera technologies. Researchers working in the NIR and SWIR spectral regions can benefit from our latest InGaAs cameras, which utilize highly advanced two-dimensional focal plane arrays.
Princeton Instruments also continues to set new technological standards with our multi-grating monochromators and spectrographs. Leading-edge instrumentation includes IsoPlane imaging spectrographs, LS Series lens spectrographs, TriVista triple-spectrograph systems, and SpectraPro imaging spectrographs.
High-precision mirrors, filters, and coatings from Acton Optics & Coatings, whose history of innovative design and manufacturing processes began in the early 1960s, are also available from Princeton Instruments.
