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.
摘要翻译：根据本发明，通过美国专利公开的方法的改进形式制造过滤器。 No. 7,068,430。特别地，该方法被修改以考虑由过滤材料吸收的影响。该方法的例子是制造用于传输在230-320纳米范围内的波段的紫外光透射滤波器。所得到的过滤器包括交替的高折射率和低折射率的多个硬涂层薄膜层。改进的滤波器提供高传输，尖锐的边缘斜率，以及深度和扩展的带外阻塞。与目前可用的滤波器相比，滤波器提供的传输最多三倍或更多倍，边缘斜率高达四倍，并且深度延伸的带外阻挡进一步延伸，甚至在可见光范围内。

摘要： Thin-film interference filters are constructed with a generalized pattern of layers differing in both thickness and refractive index to produce spectral responses appropriate for adjusting optical power among a plurality of different wavelength channels. Each of the layers is composed of unit sub-layers having thicknesses equal to a quarter-wavelength thickness of a monitoring beam. Interference fluctuations of the monitoring beam associated with the deposition of the unit sub-layers enable a gain-flattening filter to achieve greater manufacturing accuracy by exploiting self-correcting effects of “turning point monitoring” techniques.

摘要： An optical filter is provided which includes a plurality of hard coating layers of alternating high and low refractive index provided on a substrate and has an associated first transmission band. The filter also includes at least one additional plurality of hard coating layers including high and low refractive index layers and Herpin equivalent layers sandwiched therebetween. The additional plurality of layers has an associated second transmission band that substantially coincides with the first transmission band, but provides additional blocking at wavelengths outside the first transmission band. Relatively wide transmission bands and high blocking over an extended range of wavelengths can be achieved such that the filter is suitable for use in multiphoton fluorescence systems.
