Why 405nm?
· 405nm near-UV wavelength matches the maximum absorption peak of all mainstream UV photopolymer resins (including elastic resins for 3D printed shoes), enabling efficient photopolymerization/curing.
· Higher photon energy than ordinary LED, deeper curing depth, wider adaptability to high-viscosity, high-filler industrial resins.
DLP (Digital Light Processing) is a vat photopolymerization resin 3D printing technology.
The feasibility, efficiency, and final beam quality of coupling a laser beam into an optical fiber all depend on the characteristics of the original laser and the type of optical fiber.
,A bird laser deterrent, also called a green laser bird repeller, is a modern device that uses a 520 nm green laser beam to keep birds away from farms, warehouses, airports, and other sensitive areas. It works by projecting a moving green laser light across open spaces or structures, which birds see as a solid, approaching object rather than a harmless light. Because birds' strongest sense is their vision, this sudden visual threat triggers their natural flight instinct, making them flee immediately. Over time, they learn to avoid the area altogether.
