High-performance/high-quality fluorescence filter cubes for research that demands precise signal detection.

Nikon offers a wide range of fluorescence filter cubes with high fluorescence acquisition efficiency to support imaging of a large variety of fluorophoresand fluorescent proteins. The large product range includes longpass filter cubes for observation of single-stained samples and bandpass filter cubes suitable for detecting specific wavelengths from multiple-stained samples and unmixing.  

  • Wavelengths with an extremely sharp rising edge characteristic.
  • High transmittance from 93% to 97% (both excitation and barrier filters).
  • High fluorescence acquisition efficiency, enabling reduced excitation intensity and sample fading.
  • The HQ series filters, made of glass with high dimensional accuracy, eliminate the possibility of image shifts when superimposing multi-color images and ensure accurate imaging even in the case of fluorophores with small Stokes shifts.
