High Performance Fluorescence Dichroic Filters

Press release date: Mar 09, 2017

  • Improved Flatness, Transmitted Wavefront, and Surface Quality
  • Ideal for Fluorescence Microscopy or High Magnification Imaging Applications
  • Most Popular Cut-On Wavelengths of Fluorescence and Longpass Dichroic Filters

Our TECHSPEC® High Performance Fluorescence Dichroic Filters feature the same broad, flat transmission and reflection ranges as our popular TECHSPEC® Fluorescence Dichroic Filters, but have improved physical parameters. Special attention to surface flatness, transmitted wavefront, and surface quality have resulted in our highest level of precision yet on a filter. These rectangular filters fit into most common Nikon, Zeiss, and Olympus fluorescence microscopes. High Performance Fluorescence Dichroic Filters are a perfect complement to our TECHSPEC® Fluorescence Bandpass Filters. For specific wavelength or size requirements, numerous custom options are available.
