The UV irradiators that play an active role in the bonding of optical components... When using lamp-type UV irradiators, are the costs of UV lamps a burden? And when considering the introduction of LED-type UV irradiators, are you concerned about the costs as well? Additionally, when setting bonding conditions and selecting adhesives, are you worried about the actual illuminance on the irradiated surface? Are you having trouble controlling the irradiation time during training for new employees? Our "UV Curing Device for Optical Component Bonding" is LED-based, allowing for reduced cost burden and quantification of illuminance. Please feel free to contact us for more details. *For more information, please refer to the PDF materials or feel free to reach out to us.*
