Princeton Instruments (PI) is pleased to announce the latest addition to its Raman line of spectrographs. The Acton LS 785 was developed and optimized for Raman spectroscopy in the NIR. A proprietary refractive, 5 element f/2 lens design produces the highest quality imaging and field flatness for spectroscopic analysis in the 700 nm to 1000 nm region. A unique antireflection coating developed by the Acton Optics Coating Laboratory ensures 99.4% transmission per element over the working spectral range. The standard configuration includes a gold coated grating.
"We have combined our years of knowledge within the Raman market with our extensive experience of using optics in spectroscopy, to bring a lens spectrograph to the market with the highest throughput and best imaging performance available for Raman studies in the NIR," comments Roy Grayzel, Spectroscopy Product Manager.
The Acton LS 785 achieves 5 wavenumber resolution or better over its entire working range. The grating may be rotated via a micrometer and locked for the appropriate spectral coverage for use with the 650 nm to 830 nm lasers typically employed in NIR Raman spectroscopy.
An integrated optional edge filter with better than 8 OD laser line rejection can be incorporated into the collimating lens assembly to provide stray light rejection performance to approximately 250 wavenumbers from the laser line.
The compact, rugged design with no moving parts is very well adapted for applications requiring transportability and limited accessibility.
Coupling one of PI’s NIR enhanced CCD or ICCD cameras to the Acton LS 785, creates a NIR Raman Spectrometer system with unmatched sensitivity and reliability.
Princeton Instruments designs and manufactures high-performance camera, spectrograph and optics solutions for the scientific research, industrial imaging and OEM markets. Continuous innovation in R&D and manufacturing process, coupled with a customer driven paradigm ensures our customers are always at the forefront of technology and reliability while pushing their boundaries of discovery. |
