UV Spot Curing for Optical & Photonics Assembly
Optical and photonics assembly lives on alignment held to a fraction of a degree and bonds cured without stress or heat. UV-cure optical adhesives let you align, then freeze the alignment in seconds, no thermal soak, no drift, cured straight through the glass.
Optical bonds cure through the optic to the joint, so wavelength has to pass the glass and the adhesive must be low-shrinkage to avoid distorting the wavefront. Fiber termination needs a fast, even ferrule cure that doesn’t move the fiber. Broad spectrum handles any qualified optical adhesive; matched LED suits a settled 405 nm line.
Recommended Systems
Broad spectrum cures any optical adhesive and its longer wavelengths pass through most optical glass; add the heat filter (UV2554) to protect the optic.

Questions
What UV adhesive system is best for bonding optics?
A broad-spectrum SunSpot 2 cures whatever low-stress optical adhesive you qualify and its longer wavelengths pass through most optical glass; pair it with the heat filter so infrared doesn’t distort the optic. For a 405 nm optical adhesive on a fixtured bench, a matched SkyBeam channel works well.
How do you cure fiber-optic connector epoxy?
Aim a spot source at the ferrule and cure the qualified dose in seconds, far too fast for the fiber to drift, unlike an oven soak. A dual-pole splitter cures two connectors at once; balance the legs with a radiometer.
