Fusion UV Dichroic Reflectors

Dichroic reflectors are ideal for UV curing processes on heat-sensitive substrates as they minimize heat reflection onto the substrate. These reflectors can easily retrofit into existing Fusion UV microwave-powered irradiators or be used in new UV curing systems. Learn more about this solution.

Dichroic reflectors are exactly the same dimensions as a conventional reflector in Fusion UV microwave-powered UV curing systems, but have 50 or more dielectric coating layers applied to their surface. This coating reflects the UV, but absorbs much of the longer infrared (IR) wavelengths. This IR heat then dissipates from the reflector surface by air-cooling. Our reflectors are available as Standard Dichroic and Dichroic Plus versions.

  • 50 or more layers of dielectric coating on reflector surface absorbs IR energy
  • Identical dimensions to standard UV curing system reflector
  • Standard Dichroic Reflector – designed primarily for use with “D” bulb, inks, and some comparatively slow processes.
  • Dichroic Plus Reflector – provides enhanced reflectance in the UVC band (200-260nm) for improved surface cure typically with “H” bulbs
