UV meter, 220nm, recommendations for purchase

Started by Klaus Kragelund October 20, 2023
Hi

I need to purchase a UV meter to measure on a UV driver.

Wavelengt is 220nm.

Can anyone recommend a good cheap variant?

I have been recommended:

 USB2000+

and from:

Regards

Do you want a spectrometer, or just a power meter? Cheers Phil Hobbs -- Dr Philip C D Hobbs Principal Consultant ElectroOptical Innovations LLC / Hobbs ElectroOptics Optics, Electro-optics, Photonics, Analog Electronics

I need to monitor the entire spectrum to make sure the energy is placed in the right wavelength, so a spectrometer. It's for a UV excimer lamp, and I am looking into the best way to drive the lamp.

The current drive method is a flyback converter where the lamp is just placed on the output of the flyback transformer, so it sees a high voltage pulse during the flyback interval of several kV. Apparently this is the way these kinds of lamps are driven.
