UV-VIS & VIS-NIR Spectrometers

Great Versatility

We offer general-purpose UV-VIS and VIS-NIR spectrometers that are preconfigured -- where all of the optical bench options are already selected. By switching out light sources and sampling accessories, these spectrometers can measure absorbance in solutions or reflectance of solids.

200-850 nm UV-VIS Preconfigured Spectrometer

The USB4000-UV-VIS utilizes the "USB" (also called the "S") Optical Bench. It has a 200-850 nm wavelength range and comes with a detector upgrade for working in the UV, a variable longpass detector filter for second- and third-order rejection, and a 25-;Um slit as the entrance aperture. Optical resolution is —1.5 nm (FWHM).

350-1000 nm VIS-NIR Preconfigured Spectrometer

The USB4000-VIS-NIR spectrometer also utilizes the "USB" (also called the "S") Optical Bench. It has a 350-1000 nm wavelength range and comes with a 25-;Um entrance slit and a variable longpass detector filter for second- and third-order rejection. With this optical bench configuration, the USB4000-VIS-NIR achieves ~1.5 nm optical resolution (FWHM).
