Dichroics and Filters for FACS Systems

To adjust new lasers and dyes in FACS systems it will be necessary to mount new dichroics and bandpass filters. Many systems allow an easy change of these optical filters in their system (FACS Aria, MoFlo, CyFlow....) by means of changing the filterholder. AHF analysentechnik AG offers these specific dichroics for many laser applications as well as dye specific narrowband bandpass filters, blocked against laser light from all different laser sources.

Angle Tolerant Dichroics

The spectral data of interference filters are by nature very dependent on the angle of incidence. Typically the dichroics are defined for the 45 degrees angle of incidence (AOI). AHF analysentechnik offers dichroics for special geometries like 11 degrees AOI. Small optical systems often require dichroics with non- typical data, such as 31 to 59 degrees angle of incidence (e.g. defined by the optical data of the lenses) AHF analysentechnik offers different versions of angle tolerant dichroics: The spectral shift will just be half as wide as in comparable standard dichroic designs. more
