39000 series

Chroma’s 39000 series consists of our standard AT sputtered bandpass filter sets. These affordably priced filter sets provide the same durability and longevity as our premium ET filter sets, with transmission levels >90%, and are covered by Chroma’s lifetime warranty.
AT filter sets are the perfect choice for routine fluorescence detection and assays, and for most applications requiring accurate color discrimination and excellent out-of-band blocking. For zero-pixel-shift image registration, and for applications requiring the highest possible signal intensities, please refer to our ET filters.
