Choosing Filters

We have created filter sets for the multitude of fluorochromes that are typically used in epi-fluorescence microscopy. We are aware that there are applications which require filter combinations that are not listed. Often we can create such sets out of the large collection of special-order filters and dichroic beamsplitters that we maintain in inventory, and occasionally we have to manufacture newly designed filters and/or mirrors. We understand the limitations of the research budget and in either situation we try to keep prices within reasonable limits. Please contact us for help in creating filter combinations that you do not find in the catalog.

Additionally, Chroma manufactures filters for a variety of instruments including gene chip readers, high throughput systems, plate readers, flow cytometers, confocal and multi-photon microscopes, Raman spectroscopy and single-molecule microscopy.

Often the manufacturers of these instruments provide specifications for the filters that they recommend. Sometimes you may wish to order filters that are different from their recommendations and sometimes the manufacturers of bioassays have their own recommendations.

Please contact us for custom sets and recommended filter sets for standard bioassays.

Tips for Ordering Filters

Consider the following questions/answers that are extremely helpful when discussing the appropriate filters or filter sets for your application.

  • Which fluorochrome(s) is (are) being used?

  • What is the wavelength range of excitation and emission for those fluorochromes with which we are not familiar?

  • What is the make and model of the microscope or instrument being used?

  • What is the size of the excitation and/or emission filters if a filter wheel is being used in either the excitation or emission path?

  • Does the filter need to be image quality or not?

  • This is particularly important for absorption-type emission filters.

  • What is the maximum thickness possible in the filter mount to be used?

  • What type of detector is being used e.g. PMT, CCD, film)?

  • What are the specific reflection and transmission requirements for the dichroic beamsplitter?

  • Dichroic beamsplitters are designed with various spectral profiles.

  • No dichroic beamsplitter reflects all wavelengths short of the cut-on wavelengths, nor can it transmit all wavelengths beyond that point.

  • Being as specific as possible will increase your chances of getting the beamsplitter that you require and will diminish the possibility of paying too much for a beamsplitter that is more than you require.

  • It is best if we know the excitation and emission filters being used.

  • This information is particularly important when ordering a dichroic beamsplitter in the absence of any other filters.
