| Zusammenfassung: | The utility model relates to a wavelength progressive drifting light splitting coated product, which comprises an optical filter substrate, an upper film layer arranged on the upper surface of the optical filter substrate, and a lower film layer arranged on the lower surface of the optical filter substrate, an upper film Ti3O5 layer and an upper film SiO2 layer are arranged on the upper film layer, and a lower film Ti3O5 layer and a lower film SiO2 layer are arranged on the lower film layer. The total number of the upper film layers and the total number of the lower film layers are respectively 28-32, the total thickness of the upper film layers is 1700-1900 nm, and the total thickness of the lower film layers is 1700-2100 nm. The coating product for wavelength progressive drifting light splitting is formed by coating mainly by adopting a magnetron sputtering coating technology, and meets different light splitting requirements of different positions of the same optical filter on the LCD projector.
