Figure 1 shows typical spectral radiant intensity of a gas burner flame (city gas), tungsten lamp, and the sunlight on
the earth’s surface, along with UVTRON spectral response characteristics. As this figure shows, the UVTRON has no
sensitivity in the visible range and is only sensitive to ultraviolet light in a very narrow region of spectrum.

The UVTRON is a sensor sensitive only to ultraviolet light with wavelengths shorter than 260 nm. Featuring high
sensitivity high output, and high-speed response, the UVTRON is the ideal sensor for detecting flame and electrical
discharge phenomena.
