CAMERA INTERFACE SCHEMATIC

The schematic diagram shows a basic system interface using Lumencor’s CIA to precisely control the camera while optimizing imaging speed. In this configuration, the SPECTRA can either be a master or a slave component of the system. In master mode, the CIA defines image capture duration via the camera’s trigger input and uses the camera’s exposure out signal to turn on and off the light engine. The CIA then repeats the trigger process when it receives the frame ready signal from the camera. In slave mode, the CIA monitors the expose out signal from the camera to turn on and off the light engine.  Both of these methods eliminate delays in the image capture setup time. Moreover, they preserve sample viability by reducing the amount of light the sample sees during image acquisition.

SPECIFICATIONS

SOLA and RCA setup (no PC)
In this configuration, the RCA is stand-alone and communicates with the light engine via the RS-232 serial cable to send commands for on/off control of the light output and for adjustment of the output power level (0-100%). Power for the RCA comes from the AC-to-DC power supply (country-specific) that plugs into the USB-mini connector on the back of the RCA. The yellow toggle switch on the RCA is used to turn on/off power to the RCA. In addition to the on/off control of the source via the RCA keypad, the SOLA light engine may also be turned on/off manually with an external switch (e.g. foot switch, optional purchase) or by the expose out signal from a camera connected to the RCA. A DIN-to-BNC(dual) adapter is included with the RCA for this purpose. The switch or camera is connected to one of the two BNC connectors and then must be configured in the RCA SOLA menu.

SOLA and RCA setup (with PC)
In this configuration, both the PC and the RCA can communicate with the light engine via the RS-232 serial cable to send commands for on/off control of the light output and for adjustment of the output power level (0-100%). Power for the RCA comes from the USB-to-USBmini cable connected between the PC and the RCA. This cable also provides communications between the PC and the RCA and/or the SOLA. The yellow toggle switch on the RCA is used to turn on/off power to the RCA. In addition to the on/off control of the source via the RCA keypad, the SOLA light engine may also be turned on/ off manually with an external switch (e.g. foot switch, optional purchase, not pictured) or by the expose out signal from a camera (not pictured) connected to the RCA. A DIN-to-BNC(dual) adapter is included with the RCA for this purpose. The switch or camera may be connected to one of the two BNC connectors and then must be configured in the RCA SOLA menu.

Quantitative Analysis:

Constant current
Available today.
The light engine circuity monitors the current through each source and keeps it constant. Once thermalized, the power output is constant for constant ambient temperature and pressure and the pulse to pulse reproducibility is better than 99%. Performance bests the arc lamps but light engine outputs can be influenced by a function of warm up, duty cycle, power and atmospheric conditions.

Metered dosage
Offered today to OEMs willing to adopt metering electronics into their light engines.
Here a portion of the light engine output beam, internal to the light engine, is monitored. When the light engine’s internal counter reaches a desired dosage, the light is turned off. The output is locked into the photon number and dosage is not susceptible to atmospheric influences.

Constant intensity
Offered today to OEMs willing to adopt constant intensity electronics into their light engine. Broad release in 2012.
To maintain the same power per unit time, Lumencor employs a circuit that monitors the light and adjusts intensity in real time. This is most applicable for rolling shutter camera applications.
