Optical Irradiation

Optical stimulation of samples can be used as trigger for chemical reactions, sample treatment or measurement of optical excited radicals. A variety of narrow or wide band excitation sources of different intensities or spectral compositions are available.

Optical Stimulation Unit

The Optical Stimulation Unit allows irradiation at definite wavelengths.

  • Integrated light source for irradiating ESR samples

  • Holder for precise positioning included

  • Direct operation through ESRStudio for fastest response times (a few microseconds)

  • Suitable to trigger kinetic experiments

  • High-power LED

  • Intensity changeable from 100 % down to 1 %

  • Available wavelengths: 365 nm, 462 nm, 523 nm, 590 nm, 625 nm, 850 nm


External irradiation units

The External irradiation unit allows irradiation of a continuous spectrum.

  • Hg-Xe light source for irradiating ESR samples

  • Holder for precise positioning included

  • Operation through ESRStudio, response times of several milliseconds

  • High-power Hg-Xe lamp (up to 200 W)

  • Intensity changeable from 100 % down to 1 %

  • Available spectra: Ultraviolet (240 nm to 400 nm) & Visible light (400 nm to 700 nm)
