Light sources

Microscope fluorescence light sources.

Aurox has selected a range of metal halide and LED based fluorescence light sources which are compatible with the Clarity and are ideal for applications in live cell imaging.

The following fluorescence light sources are available for order from Aurox, either as stand-alone units or as part of a Clarity microscopy system:

CoolLED's pE-300Ultra offers intense, broad-spectrum LED illumination for imaging the most common fluorescent stains with microsecond switching via multiple TTL inputs and the ability to mount inline excitation filters.

Pairing with high performance multi band filter sets enables imaging traditionally requiring a white light source and filter wheel.


  • Clean bright cross spectrum illumination
  • Specify for existing single and multi-band filter sets
  • Instant on/off
  • Simple installation and use
  • Stable and repeatable
  • Adapters to fit most microscopes
  • Precise intensity control in 1% steps (0-100%)
  • Excellent uniformity over field of view
  • Lamp life expected >25000 hours of operating time
  • Removable inline excitation filter holders
  • Individual microsecond channel triggering via TTL
  • Sequenced excitation from a single TTL-out with Sequence Runner

The CoolLED pE-4000 is a broad spectrum (365-770 nm) illumination system for fluorescence microscopy with 16 selectable LED wavelengths that can be matched to the filters and fluorophores of almost any microscope.

For consistency and ease of use the system can be operated as a ‘White’ illumination system using simple on/off and intensity buttons, or in “Advanced” mode for total control of the excitation source for improved imaging and for selection and control of individual wavelength settings.


  • Broad LED spectrum: 365 – 770 nm
  • Four channel wavelength-grouping design
  • Individual control of selected LED wavelengths
  • Instant on/off - no shutters, no warm up or cool down
  • Precise intensity control in 1% steps (0-100%)
  • Excellent uniformity over field of view
  • Lamp life expected >25000 hours of operating time
