Dyna-Film filters are a custom designed and manufactured range of filters to optimize spectral performance, provide exceptional environmental durability, and minimize the cost of optical bandpass filtering required for absorbance, reflectance, and transmissive applications. Dyna-film bridges the gap between traditional bandpass filters and expensive sputtered films. Dyna-Film filters will benefit many instrument manufacturers which require the following critical spectral and physical performance characteristics: high transmission, deep blocking, great environmental durability, lower cost. Dynasil manufactures Dyna-Film filters through Optometrics. Please contact Optometrics directly to discuss your high transmission bandpass filter needs.
Optical interference filters reflect and transmit one or more spectral bands while maintaining a near-zero coefficient of absorption for all wavelengths of interest. An interference filter may be high transmission, low transmission, band transmission, or band blocking. Dynasil designs and manufactures optical interference filters through our company, Optometrics. Optometrics produce a broad range of optical interference or dichroic filters.
Traditional bandpass filters are used to selectively transmit a narrow range of wavelengths while blocking all others. This type of interference filter finds wide application in spectral analysis, particularly in: clinical chemistry, spectral radiometry, environmental testing, laser line separation, flame photometry, and color separation where the required wavelengths are well known. Dynasil manufactures traditional bandpass filters through Optometrics. Please contact Optometrics directly to discuss your bandpass filter needs.
