Product Description: The LP560 nm filter (Long-Pass 560 nm) is a long-pass optical filter that blocks all short wavelengths below 560 nm (especially the ultraviolet-blue light range), allowing only visible to near-infrared light ≥560 nm to transmit efficiently. It serves as a core component in various applications such as aesthetic photon therapy, imaging detection, and laser protection.I. Spectrum and Performance• Cut-off Wavelength: 560 nm ± 3 nm (T50% point)• Transition Steepness: ≤ 20 nm (transmittance rises from 5% to 80% at 560 nm)• Peak Transmittance: T ≥ 94% (average from 580-1100 nm)• Blocking Depth: OD2-OD4 (transmittance ≤ 0.01% from 200-550 nm)• Surface Quality: 60-40 scratch-dig; surface figure 1/4λII. Process and Specifications• Coating: IAD ion-assisted multilayer dielectric hard coating, dense film layer, resistant to over 500 alcohol wipes• Substrate: B270, D263T, fused silica, or sapphire (thickness optional from 0.3-5 mm)• Dimensions: Round discs Ø3-Ø110 mm, square pieces 2×2-146×146 mm, custom-shaped holes and chamfers available according to customer drawings• Environmental Testing: -40 ℃→+85 ℃ cycling for 48 hours without coating detachment or cracking, compliant with MIL-STD-810F standardIII. Typical ApplicationsIPL Aesthetic Photon Skin RejuvenationUsed in conjunction with intense pulsed xenon lamps to block harmful UV-blue light, retaining only the therapeutic wavelength range of 560-1200 nm for skin whitening, rejuvenation, spot reduction, and redness removal.Machine Vision and Fluorescence DetectionAfter blocking excitation light below 560 nm, the camera only receives emission fluorescence above 560 nm from the sample, improving the signal-to-noise ratio. more>
