Pingzhi Optics Beauty Instrument for Skin Rejuvenation and Hair Removal, Long - Wave Pass Filter With a Wavelength of 610nm
LP - 610nm Long-pass Filter. Long-pass filters, also known as long-wavelength pass filters, as an important optical component, are widely used in fields such as digital imaging, biomedical beauty, and fingerprint recognition. Its characteristic is to allow light within a certain wavelength range to pass through while blocking light within another wavelength range. It has features such as high transmittance, wide cut-off band, and good film layer firmness. Filter products are produced according to the customer's index requirements.

Long-pass filters are a commonly used filter solution in beauty instruments. Its principle is that a high-intensity pulsed xenon lamp emits a wide-spectrum light. By using a specific filter to filter out ultraviolet light and select the standard spectral band for the treatment range, it acts on human skin tissue to achieve the effect of beauty treatment. The difficulties in the film system design and preparation process of related filters lie in the requirements of high pass-band transmittance, wide cut-off band, and high steepness for such filters.
