SPEC RES+ / SPEC RES+ Vis/NIR

​• Wavelength range: 380-1050 nm
​• Optical Resolution: 0.6 nm
​• 3648 pixels Toshiba CCD array detector
​• 600 grooves/mm grating blazed at 750 nm
​• Order Sorting Filters Included
​• Software LightScan included

Covering the entire visible and most of the NIR range with high resolution, the SPEC RES+ Vis/NIR is configured with a 600 grooves/mm blazed at 750 nm grating, 10 µm slit, Toshiba 3648 pixels CCD array, collecting lens, longpass filter and SMA 905 optical fiber connector. 

There are a wide range of applications on Spectroscopy using Visible and NIR light where we can mention transition metals due to their ability to complex with organic and inorganic molecules which absorb in the visible region and can be qualified and quantified by this technique, and in the analytical third overtone region (700-1050 nm) where are normally found absorbance bands related to ROH, H2O, CH, CH2, CH3, ArCH, ArOH, RNH2.

The measurement techniques applied to this instrument are high resolution Absorbance, Transmission, Irradiance, Reflectance and color measurement. The application areas are Chemistry, Physics, Biology, Materials, etc.

The spectrum on the right shows the full spectra of a Mercury/Argon light source and on the left shows the Argon doublet 840.821 and 842.465 nm completely resolved.
