Cairn’s xenon arc light source delivers ultra-high stability and high-intensity illumination, making it ideal for fluorescence microscopy due to its high point intensity and broad spectrum. The modular design and wide range of couplings ensure that it can be equally effective for other purposes, providing versatility for diverse scientific applications.

The OptoSource is configured to produce intense, focused light, perfect for coupling either with our OptoScan monochromator or directly into a light guide. For optimal performance, we only recommend the 75W lamp when used in combination with the OptoScan.

Application Usage

  • Fluorescence microscopy
  • Calcium imaging
  • Voltage Sensitive Dye measurements
  • Photoactivation
  • Solar emulation

Features and Benefits

  • Ultra-high stability power supply and lamphouse design with external thermistor-controlled fan for critical applications
  • Ellipsoidal reflectors for high light-gathering efficiency without spherical or chromatic aberration
  • Balanced proprietary low-impedance igniter circuit incorporated inside the lamphouse for low interference emissions at switch-on
  • Optosource lamp housings use a dielectric-coated ellipsoid reflector optimised for peak reflectance between 300nm and 500nm (other coatings are available to order)
  • Couplings to all popular fluorescence microscopes
