Spectrometer by Light Machinery

Note: Your Quotation Request will be directed to Light Machinery.

The HF-8995-3-PLASMA from Light Machinery is a NIR Spectrometer that operates at a wavelength of 775 nm - 900 nm. It has a spectral resolution of 0.9 pm (or 0.01 cm-1) and a wavelength accuracy of ±20 pm. This spectrometer has an sCMOS image sensor with a dynamic range of 9000 and a quantum efficiency of 40%. It has a noise ratio from 100:1 to 500:1 and an acquisition speed of over 10 Hz. This spectrometer has a simultaneous range of 9 nm and resolving power of 1 million. It has a slit width of 5 µm, a numerical aperture of f/6, and a throughput of 10%. This spectrometer can be controlled via a USB interface.

The HF-8995-3-PLASMA has no moving parts which enables it to perform fast single-shot laser spectrum analysis, quick data acquisition, and export. It can measure fine features in plasmas, perform pulsed laser characterization and measure the small spectral shifts from Brillouin or Raman scattering. Simple PC-based software along with LabView drivers and C# named pipe commands enable this spectrometer to be integrated into automated experimental setups. 

The HF-8995-3-PLASMA is available in a package that measures 700 x 150 x 400 mm and has 105 µm SMF/MMF fiber with FC/PC connector. It is ideal for plasma spectroscopy, high-precision gas spectroscopy, femtosecond comb fingerprinting spectroscopy, spectral-domain optical coherence tomography, solar spectroscopy, brillouin spectroscopy, astronomical spectroscopy, raman and ultra-low frequency raman, undergraduate physics and chemistry laboratory applications.
