Dichroitic short-pass, bandpass and long-pass filters

Additional layer systems [Hard, scratch-resistant anti-reflex layers

 

Dichroitic filters function on the basis of interference in connection with multiple reflections of thin dielectric layers which have been applied by a vacuum-vaporization process. Filters of this kind are frequently used in many different kinds of technical applications. Their effect on the radiation penetrating them is, among other things, represented by the spectral transmission t [%] as a function of the wave-length l [nm].

Customs coatings on request. Please send us your specification. As a description of the transmission characteristics, we recommend ISO 9211-2. Below you can see some example curves.
