Calculating Output Power
You can estimate the power in the collimated beams* at any wavelength or in any wavelength range from our Series Q, Apex, or Research Lamp Housings with any of our CW and pulsed arc, ...
Tutorials
Resolution of Monochromators and Spectrographs
Gratings are available in various groove densities (i.e. lines/mm). Higher groove densities give higher reciprocal dispersion and therefore higher resolution. The grating dispersion ...

Oriel Instruments
Oriel products and solutions represent leading instruments, such as light sources covering a broad range from UV to IR, pulsed or continuous, and low to high power.
Technical Notes
Simulation of Solar Irradiation
Oriel® Solar Simulators provide the closest spectral match to solar spectra available from any artificial source. The match is not exact, but better than needed for many applications. ...
Technical Notes
Solar Simulator Standards
A solar simulator is a light source that approximates the illumination of natural sunlight. The ability of a solar simulator to approximate natural sunlight is based on three criteria: ...
