SPEC STD / SPEC STD UV/Vis
• Wavelength range: 180-880 nm
• Superior UV sensitivity
• Optical Resolution: 1.4 nm
• 600 grooves/mm grating blazed at 300 nm
• Order sorting filters included
• Optional Enhanced Sensitivity version
This standard configuration includes a 2048 pixels Sony CCD array detector, 25 µm slit which offers an excellent compromise between resolution and sensitivity, 600 grooves/mm grating blazed at 300 nm, order sorting filters, mini USB for communication and power the spectrometer and SMA 905 for Optical Fiber connection.
The SPEC STD UV/Vis is a flexible, multi application spectrometer for users that need to measure in the ultraviolet and visible regions. It’s suitable for a wide range of measurement techniques, including Absorbance, Transmittance, Reflectance and Irradiance.
All STD UV spectrometers have the CCD coated for high UV sensitivity that extend UV range down to 180 nm (in the spectra below is clearly visible the 184.95 nm line of Mercury).
We strongly recommend the Enhanced Sensitivity option for reflection measurements when the sample has low reflectivity, in irradiance measurements of low power emission sources and applications where high UV sensitivity is required.
The image below shows the spectrum of a Mercury Argon lamp detected by the SPEC STD UV/Vis.
