06 Feb 2007 DYMAX optical precision UV adhesives offer various advantages over alternative assembly technologies: The “cure on demand” property allows for the precise alignment of parts before cure. Minimal shrinkage during cure and the excellent adhesion to a wide variety of substrates are ideally suited for optical manufacturing.
To best support these adhesive properties DYMAX has developed the new UV spot lamp system BlueWave 200 with integrated intensity adjustment. This technical feature allows for the exact determination of the required intensity to reach fast, low-shrinkage cure of the adhesive with minimized heat development to protect sensitive parts. Furthermore, the feature secures the consistency of the adhesive curing process by allowing for a constant intensity level during production.
Intensities of more than 17 W/cm² render the BlueWave 200 into a powerful UV spot curing system. The device primarily emits UVA and visible light (300 - 450 nm) and matches precisely the curing needs of photoinitiated adhesives. Until now, a decrease in intensity over time has been an inherent problem in UV bulb technology (discharge lamp). However, the intensity adjustment feature allows users to take control of the desired intensity level. The adjustment compensates for the decline due to aging. A removable knob at the front panel gives the user easy access to the precise manual adjustment of the emitted intensity level (for verification a radiometer such as the DYMAX Accu-Cal 50 is used directly at the end of the light guide). In optical assemblies this intensity control feature supports yielding consistent high quality and high performance bonds.
In automated manufacturing environments the DYMAX BlueWave 200 communicates with PLCs via its I/O-Port. Alternatively the UV spot system can be activated using the foot pedal. Complemented by the DYMAX Accu-Cal 50 Radiometer the BlueWave 200 significantly helps to ensure high quality assemblies for optical precision manufacturing.
