AURA light engine®

Ideal OEM Illumination Platform for Biophotonics

Lumencor’s AURA light engine is a high performance, state-of-the-art, bright set of solid state light sources.  It can be tailored to provide for the spectral, spatial and temporal needs of the bioanalysis tool it is designed to support. Key features of the AURA light engine include:

  • Up to 5 independently controlled (on/off and intensity) light sources
  • A selection of outputs ranging from ultraviolet to near-infrared
  • High performance bandpass filters or unfiltered white light
  • Fast (~10 μs) switching between color channels
  • 100–700 mW optical output power per channel (dependent on filtering)
  • Light guide or optical fiber coupling for vibrational isolation
  • Vertically or horizontally oriented installation options
  • TTL and serial control interfaces

Application-Specific Customization of Solid-State Illumination

Solid-state light engines are now displacing mercury, metal halide and tungsten-halogen lamps in many bio-optical applications. This trend is driven by a wide range of economic and performance benefits. Light engines are less expensive to operate and maintain than lamps because there are no bulbs or light guide replacements required. Output stability and electronic control of output intensity are dramatically superior to the decay, noise, flicker of any bulb. 

An article by Lumencor’s Director of Technical Support, Iain Johnson, in the February 2017 issue of Laser Focus World describes how these benefits can be leveraged to deliver illumination solutions tailored for specific applications.

Metered Dosage

Could You Use Some Feedback?

The ability to control the input quantity of the light “reagent” is a critical factor in obtaining predictable and reproducible outputs from photochemical processes. Controlled light delivery for applications such as quantitative fluorescence microscopy, photodynamic therapy (PDT) photolithography and optogenetics requires intelligent light sources equipped with output monitoring and feedback systems.

At Lumencor, we refer to quantitative light delivery as metered dosage. The necessary monitoring and feedback systems can be optionally installed in all SPECTRA light engine®, SPECTRA X light engine® and AURA light engine® models.

Open loop and closed loop metered dosage systems are available. In both schemes, an onboard photodiode continuously monitors the light output and generates a reference signal. In open loop monitoring, the reference signal is delivered for external display or processing via a BNC connector on the rear panel of the light engine. In the closed loop metered dosage scheme, the reference signal meters the light output and shuts it off when a user-input time-integrated intensity threshold is reached. All closed loop metered dosage functions are controlled from a serially connected computer.

  • Discrete spectral outputs of 4 solid state light sources are electronically selected and combined according to application requirements.
  • The spectral output of each source may be refined by filtering (F).
  • Optionally, light engine output may be monitored by a reference photodiode (rPD) to provide feedback control.
