摘要： In accordance with the invention, a filter is fabricated by a modified form of the process disclosed in U.S. Pat. No. 7,068,430. In particular, the method is modified to take into account the effect of absorption by filter material. The method is exemplified by the fabricating of an ultraviolet light transmission filter for transmitting a band within the range 230-320 nanometers. The resulting filter comprises plurality of hard-coating, thin-film layers of alternating high and low index of refraction. The improved filter provides high transmission, sharp edge slopes, and deep and extended out-of-band blocking. As compared with currently available filters, the filter provides transmission up to three or more times greater, edge slopes up to four times sharper, and deep extended out-of-band blocking extending further, even through the visible range.

摘要： High performance optical edge and notch filters and methods of making the same are disclosed. The multi-layer, thin-film optical edge filters have an edge steepness greater than about 0.8% as measured by dividing (a) the edge width from the 50% transmission wavelength to the optical density 6 (“OD6”) wavelength by (b) the 50% transmission wavelength. The optical edge filters also have an average transmission above about 95%. The notch filters exhibit a blocking of OD>6, very high transmission (>90%) outside the notch(es), and a narrow notch bandwidth comparable to that of holographic notch filters. The methods for making such filters accurately determine when deposition of each layer of the filter should terminate.

摘要： Highly discriminating optical edge filters and methods of making the same are disclosed. The optical edge filters have an edge steepness greater than about 0.8% as measured by dividing (a) the edge width from the 50% transmission wavelength to the optical density 6 (“OD6”) wavelength by (b) the 50% transmission wavelength. The optical filters also have an average transmission above about 95%. The methods for making such filters accurately determine when deposition of each layer of the filter should terminate. The methods include calculating theoretical transmission data for a layer of the filter and calculating an expected deposition duration for the layer. The methods also include measuring transmission through the layer during deposition for a period less than the expected deposition duration. When the measuring period elapses, a new deposition duration is calculated based upon the theoretical transmission data and the measured transmission data, thereby providing an accurate deposition duration for the layer.
