Acton LS 785High-Throughput NIR Spectrometers

Acton LS photo

The Acton LS 785 is a high-throughput, lens-based spectrograph ideal for NIR spectroscopy. With a fast f/2 optical system with proprietary AR-coated lenses it is optimal for NIR transmission.

  • Fast f/2 optics over the 750 – 1100 nm wavelength range
  • High-transmission, AR-coated elements
  • Micrometer-controlled grating rotation and focus adjustment
  • Compatible with fiber probes for Raman spectroscopy

Key Features

NIR Raman Spectroscopy

The LS-785 gives users a significant advantage in both acquisition time and spatial integrity for Raman spectroscopy applications. When combined with the PIXIS or PyLoN deep-depletion CCD detectors, the LS-785 delivers the highest possible throughput and performance.

NIR Optimized Parameters

The Acton LS-785 has an f/2 reflective optic with a working range between 750 – 1100 nm, ideal for NIR spectroscopy.
