New laserfilters for UV (375nm) or blue (405nm) laserdiodes nm are available out of the new hardcoating filtertechnique from Semrock comp. They will guarantee maximum efficiency to excite the fluroescent sample with a high transmission filter which a bandbass from 370 to 410 nm. In combination with a hardcoated fluorescence emitter and precisely matched dichroic beamsplitter optimum fluorescence signals can be detected. This filterset will be delivered completely mounted from AHF analysentechnik in filtercubes for all series of microscopes. Additionally singleband or multiband filtercombinations for blue/green/red laserdiode set-ups can be precisely matched to the individual demands of the research groups.
