 Xenon Light Source 300W Monochromatic Light with Filters

product model MAX-303
figure MAX-303 Optical System
Extremely bright and heatless light source which can illuminate desired wavelength

The MAX-303, 300W xenon light source, is the perfect illuminator with complete heat blocking design, using an originally designed mirror module.
The MAX-303 has all useful functions such as mirror module, filter wheel, ND variable control, timed shutter and remote control.

Monochromatic light output by optical filter

  • Bright monochromatic light
  • Instead of multiple wavelength laser
  • Output beam is brighter than monochromator
  • Selectable various wavelength by optical filters
  • Unwanted IR heat and stray light are removed by mirror module

UV light output without IR heat

  • A bright UV light with desirable wavelength range
  • UV light with blocking IR heat
  • It is also possible to obtain a desirable UV wavelength range with
    the combination of a mirror module and optical filters.
    *If you would like to know about a combination of filters, please contact us.
