AHF offers the next generation of solid-state illumination. CELESTA and ZIVA from Lumencor provide the performance you need for advanced imaging. 

AHF analysentechnik offers the new light engines CELESTA and ZIVA as well as CELESTA quattro and ZIVA quattro from Lumencor. These light sources are equipped with seven respectively four individually addressable solid-state laser sources. The CELESTA provides ~1 W/mm² sr and ZIVA 400 W/mm² sr output power from each laser source. The laser outputs are allied to sophisticated control and monitoring systems to deliver the performance needed for advanced imaging applications. CELESTA can be used for spinning disk confocal microscopy, optogenetics, MERFISH, super-resolution, FRAP, DNA-PAINT, the ZIVA for structured illumination (SIM) and other super-resolution imaging techniques due to its optimized multimode laser array for coupling into narrow bore optical fibers < 200µm. 

The control system of the light engines features an onboard computer with an embedded command library. These commands give access not only to the basic control functions of light source selection, on/off switching and output intensity adjustment, but also to an extensive panel of operating status reports and preference settings. A GUI resident on the onboard computer and can be viewed using a web browser via a LAN connection, provides convenient access to many of the command library functions. TTL trigger inputs are provided for all seven output lines for applications requiring fast (10 microseconds) switching. Long-term output stability is given by active stabilization. In all of the microscope software packages which are compatible with the Lumencor Spectra III these light sources can be integrated.

AHF also provides laser filter sets which match perfectly to the new light sources.
