What is Polka-Dot Technology?

Polka-Dot technology, integrated in the AZURA DAD 6.1L, ensures a seamless blending of UV light deriving from the high brightness (and long life) deuterium lamp and VIS light deriving from the halogen lamp. The proportion of light stemming from each source is regulated via a Polka-Dot design, to optimized the light intensity over the entire 190 - 1000 nm spectrum. This provides excellent sensitivity over the whole wavelength range.
