In uvled, the ultraviolet light in the 365nm band belongs to the pure ultraviolet light output, and the monochromatic light does not contain infrared rays, which avoids the cured part from being affected by the radiation in the light band beyond 350nm~400nm. The UVLED light curing machine with a wavelength of 365nm can effectively reduce the temperature rise of the illuminated workpiece because it does not contain infrared rays and radiant heat. It is more suitable for processing applications that require low temperature, high precision and minimum thermal deformation of bonding, such as optical lens assembly , and usually the wavelength band of curing uv glue is also 365nm.
