The fiber focus lens at the injection stage is the optic that makes that work — it couples two different wavelengths into the same fiber cleanly enough that energy stays stable across the full spot-size range, not just at one configuration.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThat dual-wavelength, wide-spot delivery places a heavier demand on the focus lens than a typical single-wavelength setup. Both 755 nm and 1064 nm have to enter the fiber with consistent convergence, and the coupling must hold up under the high pulse rates Clarity II is built for. Contamination, coating wear, or any drift in the optic shows first as reduced coupling efficiency, then as inconsistent output across spot sizes — particularly at the larger end of the range where the energy budget is tightest.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eReplace the lens when output stability starts to drift between treatments, when the surface shows contamination or coating degradation, or as part of scheduled optical service on the delivery path. A clean, correctly seated optic restores the dual-wavelength coupling that the Clarity II's single-fiber design depends on.\u003c\/p\u003e\n\u003cp data-start=\"2032\" data-end=\"2385\"\u003e\u003cstrong\u003eTechnical Details:\u003c\/strong\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli data-end=\"2501\" data-start=\"2440\" data-section-id=\"cpwhn9\"\u003e\n\u003cstrong data-end=\"2459\" data-start=\"2442\"\u003eProduct type:\u003c\/strong\u003e Fiber Focus Lens \/ Fiber Focusing Lens\u003c\/li\u003e\n\u003cli data-end=\"2602\" data-start=\"2544\" data-section-id=\"1d96v1o\"\u003e\n\u003cstrong data-end=\"2567\" data-start=\"2546\"\u003eApplication area:\u003c\/strong\u003e Laser-to-fiber coupling assembly\u003c\/li\u003e\n\u003cli data-end=\"2680\" data-start=\"2603\" data-section-id=\"14jryt2\"\u003e\n\u003cstrong data-end=\"2626\" data-start=\"2605\"\u003eOptical function:\u003c\/strong\u003e Focuses laser energy into the fiber optic interface\u003c\/li\u003e\n\u003cli data-end=\"2821\" data-start=\"2681\" data-section-id=\"1rl1j3u\"\u003e\n\u003cstrong data-end=\"2714\" data-start=\"2683\"\u003eCommon replacement reasons:\u003c\/strong\u003e contamination, coating wear, drift across spot sizes, or weakening coupling under sustained pulse load\u003c\/li\u003e\n\u003cli data-end=\"2867\" data-start=\"2822\" data-section-id=\"8eb1wv\"\u003e\n\u003cstrong data-end=\"2838\" data-start=\"2824\"\u003eCondition:\u003c\/strong\u003e Brand new replacement part\u003cstrong\u003e\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eThis part is compatible with the following devices:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eLutronic Clarity II\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eAt LaserX Parts, we carefully select and quality-check every product to ensure only premium-quality spare parts reach our customers.\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"font-size: 0.8em;\"\u003eLaserX Parts is an independent supplier of spare parts for professional laser and aesthetic devices.
