SPEC STD / SPEC STD Vis/NIR

​• Wavelength range: 380-1050 nm
​• Optical Resolution: 1.4 nm
​• 600 grooves/mm grating blazed at 750 nm
​• Order sorting filters included

Ranging from 380 to 1050 nm the SPEC STD Vis/NIR was designed with a 25 µm slit for good resolution and sensitivity, a 600 grooves/mm grating blazed at 750 nm for maximum efficiency on the NIR region and, as all STD spectrometers, includes a Sony 2048 pixels linear CCD array, order sorting filters, SMA connector for optical fibers and a Enhanced Sensitivity version as an option.

The SPEC STD Vis/NIR is suitable for Absorbance, Transmittance, Reflectance, and Irradiance in its detection range.

In the image below (left) shows the emission spectrum of a Mercury Argon Lamp acquired with this configuration. The detailed spectrum in the right shows the well resolved spectrum of the doublet 840.821 and 842.465nm.
