Solid-State Laser Array for Advanced Imaging Applications
The CELESTA light engine delivers approximately 1 watt of output power from each of its 7 individually addressable solid-state laser light sources (7 watts total). The laser outputs are allied to sophisticated control and monitoring systems to deliver the performance needed for spinning disk confocal microscopy, optogenetics and other advanced imaging applications.

The control system of the CELESTA 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 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 7 output lines for applications requiring fast (10 microseconds) switching. Long-term output stability is sustained by active stabilization. An onboard photodiode continuously monitors the light output and generates a reference signal that is applied to the constituent sources in a feedback loop to maintain constant light output over time.
