The 1250M from HORIBA is an Infrared Spectrometer that has a spectral range of up to 1500 nm. It has a wavelength accuracy of ± 0.15 nm and repeatability of ± 0.005 nm. This spectrometer has a resolution of 0.006 nm at the exit slit with PMT and an aperture size of f/9 with a focal length of 1.25 m. It has a maximum wavelength scan speed of 4,000 steps/nm and step size of 0.00025. This spectrometer has a spectral dispersion of 0.65 nm/mm (at 500 nm) with a magnification of 1 and grating size of 110 mm x 110 mm.

The 1250M is a fully automated spectrometer with optional dual entrance and exit ports. It can be easily integrated with Synapse CCDs, a full line of single-channel detectors, and PMTS. This spectrometer has a kinematic grating mount and can be controlled via USB 2.0 interface. It is available in a compact package that measures 134.6 (L) cm x 45 (W) cm x 36.8 (H) cm and is ideal for Raman spectroscopy, Photoluminescence, Plasma Emission, LIPS (Laser-induced plasma spectroscopy), LIF (Laser-induced fluorescence) spectroscopy& LIBS (Laser-induced breakdown spectroscopy) applications.
