Optical Thin Film Technology

Mitsubishi Cable Industries can apply superior high-power laser tolerant Anti-reflection (AR) film or high-reflection (HR) film coatings on the face of various fibers.

AR film suppresses Fresnel reflection at the end surface of optical fibers, enabling highly efficient light/laser transmission. The suppression of reflected light from the end faces of fibers helps prevent damage to the laser system from back reflected laser light.
HR coating films on the output surface of fiber laser fibers enhances the amplifying characteristics of the fiber laser.


• Thin film coatings for high power laser cables are available.
• Thin films can be coated not only on LASERGUIDE®) (Laser Delivery fiber), but also on DIAGUIDE®) single core and bundled fiber cables.

Our thin film coatings are produced in house, with custom made thin film coatings matching your wavelength and application needs. (For more details, please contact us using the web-inquiry form below.)
