430nm long wave pass filter

430nm long wave pass filter is a filter solution commonly used in beauty instruments. Its principle is that the strong pulse xenon lamp emits wide spectrum light. The effect of beauty treatment is achieved by filtering ultraviolet light with a specific filter and selecting the standard spectral band for the treatment range to act on human skin tissue. The difficulty in the film system design and preparation process of related filters lies in the high band transmittance of such filters, Requirements for wide cut-off band and high steepness.
