The Acton Series LS-785 is a high-throughput, lens-based spectrograph ideal for near-IR spectroscopy. It features a fast f/2 optical system with proprietary AR-coated lenses for optimum NIR transmission. At an aperture of f/2, the LS-785 is perfectly matched to .22 NA optical fibers and achieves up to 4x the throughput of a standard f/4 mirror-based spectrograph. With its fast AR-coated compound lenses from our Acton Optics group and a custom gold-coated grating, the LS-785 provides the highest throughput and best imaging commercially available for the NIR. The LS-785 also includes micrometer-controlled grating rotation, allowing users to access the NIR between 750 nm and 1100 nm.
LS 785 features include:
Fast f/2 optics
High-transmission, AR-coated elements
Excellent image quality
Micrometer-controlled grating rotation
Micrometer focus adjustment
Seamless integration with high-performance Princeton Instruments cameras
Powerful, 64-bit
The LS-785 gives users a significant advantage in terms of both acquisition time and spatial integrity for demanding Raman spectroscopy applications. Combined with renowned Princeton Instruments PIXIS or PyLoN deep-depletion CCD detectors, the LS-785 delivers the highest possible throughput and performance.
