Illuminator Fluorescence Microscopy

OptoSource illuminator

• Designed to work with Cairn Optoscan Monochromator
• Solar emulator
• Fluorescence microscopy

Product Description

OptoSource Illuminator for Fluorescence Microscopy

Cairn’s xenon arc light source offers ultra-high stability, high intensity illumination. The high point intensity and broad spectrum make it particularly suitable for fluorescence microscopy, but the modular design and wide range of couplings ensures that they can be equally effective for other purposes.

The Optosource is configured to produce intense focussed light for coupling either to our Optoscan monochromator, or directly into a light guide.

We only recommend the 75W lamp when used in combination with the OptoScan

Additional information


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


• 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
