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.
