Our special filters convert daylight of strobes (5500 - 6500º Kelvin into blue light (450-465 nm), which is essential for fluorescence stimulation. We use a Dichroic glass filter plus a special foil, which blocks wavelenghtes higher than 500 nm. Stobes have a strong contingent of wavelenghts between 500-700 nm, which overexposes the blue wavelength up till 500 nm and prevents fluorescence. Some providers argue that a plastic foil is sufficent for good results. This is not convincing. Also my colleague Charles Mazel (MIT engineer and founder of nightsea) recommends the use of dichroic glass filters with or without additional special foil. For blue LEDs (450-460 nm) I use from the very beginning (2007) an additional dichroic glsas filter.
We integrate this dichroic filter also in very strong torches with blue LEDs (royal-blue, 450 nm), which is superior to the use of strobes. For video documentation the use of flash is anyhow excluded. In our opinion the operation of strong blue light torches (450-465 nm) in combination with a dichroic filter gives the best results, i.e. brilliant colors (rain bow) with intensive red fluorescence.
We offer different types of flter: 1. Conversion of Underwater-strobes (5500-6500º Kelvin) into blue light (450-465 nm) 2. Conversion of white LED-torches into Blue Light torches 3. Bluelight (450-465 nm ) into daylight (5500º Kelvin) Details see at Store
