480nm Longpass Filter for IPL Redness

480nm Longpass Filter for IPL Redness The 480 nm long pass optical beauty filter for IPL (LP480) has been specifically optimized for targeting superficial to nodular structures in IPL treatments and is particularly suitable for addressing facial redness and telangiectasia.  By effectively blocking wavelengths below 480 nm and transmitting wavelengths of 480 nm and above, the LP480 filter preserves the hemoglobin absorption peaks at approximately 542 nm and 577 nm, while maintaining sufficient energy concentration in the upper dermis, where facial blood vessels are densely distributed.  Clinical data indicate that the primary hemoglobin absorption peaks occur at 418 nm, 542 nm, and 577 nm.  The penetration depth associated with green to yellow wavelengths (approximately 1–3 mm) corresponds to a superficial vascular depth of about 0.46 mm.  These characteristics make the LP480 filter well-suited for the treatment of superficial and nodular vascular lesions associated with facial redness…
