Luzchem's spectroradiometers can be used for sunlight measurements, photobiology research, drug photostability testing, environmental dosimetry and curing applications. These NIST-traceable instruments will provide information in the 200-1100 nm region. They are based on either a 3648 or 4096 element diode array detector, an integrating sensor with convenient fiber optic connectivity, easy to use software, and a convenient USB interface.
Model SPR-4001 is recommended for research applications in the 235-850 nm range, and for uses requiring access to tight spots. A built-in verification lamp allows for rapid end-user check of the wavelength calibration.
Model SPR-4002 is a more robust self-contained unit recommended for environmental and tanning applications. Ideal for field work.
Model SPR-03 covers the 200-1100 nm range and offers faster integration times than our other models.
Luzchem's spectroradiometer application allows for variable integration times, from 1 ms to many seconds, either user-selected or automatically optimized by the powerful software to match the intensity level monitored. Data can be displayed as raw intensity or as a power spectrum in mW/(m2nm), using either the NIST-traceable calibration provided, or a user-generated calibration file. Luzchem also has PTFE attenuators. These can be sold including a NIST-traceable calibration.
The display includes graphic data as well as integrated spectral ranges, UVA, UVB, UVC, visible and a user selected spectral window. In the time acquisition mode Luzchem spectroradiometers display real time data and stores full spectra at user-selected intervals. Data are easily exported to common spreadsheet or graphic applications. A powerful and affordable tool for ultraviolet and visible metrology.
