Abstract: An optical filter apparatus transmits less than 5% of light within a notch spectral range about a central line wavelength with a notch bandwidth, and transmits more than 90% of light within a transmission spectral range that extends over an adjacent pass band of longer and shorter wavelengths and excludes the notch. The apparatus has a first thin film interference filter and a second thin film interference filter in the path of incident light reflected from the first filter. The first and second thin film interference filters are each treated to transmit light of the notch spectral range and reflect light of the transmission spectral range and each have thin film layers formed on a substrate, including first layers having a first refractive index, and second layers having a higher second refractive index. The notch bandwidth at full width half transmission is less than 5% of the central line wavelength.

Abstract: 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.

Abstract: High performance optical edge and laser-line 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 edge filters also have an average transmission above about 95%. The laser-line filters have an extremely high transmission in the passband (greater than 90%), an extremely narrow transmission bandwidth, and achieve blocking with an optical density (OD) greater than 5 at wavelengths that differ from the laser wavelength by less than 1% of the laser wavelength. The methods for making such filters accurately determine when deposition of each layer of the filter should terminate.

Abstract: 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.
