Unlike absorptive colored glass or polymer gels, these thin film interference filters are virtually absorption free providing superior transmission, high-contrast spectral bands, and true lifetime performance. Dichroic bandpass filters can be designed for narrow bandwidths (5 and 10nm typical) or wide bandwidths (50 and 100nm typical). They also have steep edge transitions between the high transmission bandpass and shorter and longer wavelength reflection bands much steeper than colored glass or polymer gels.

Bandpass filters are commonly matched or combined with other types of filters to optimize performance in your specific application. In many cases, an optimized OEM design combines multiple coatings onto the same optic to enhance performance, size, and weight of the device. Some of these complementary filter types include:

Custom spectral bands are available to match specific bandwidths and cut-on & cut-off wavelengths engineered for your specific application to deliver the targeted spectral output. These bandpass filters can be patterned on glass optics and wafer-level devices for integrated spectral sensing and imaging. Multiple bandpass filters can also be micro-patterned for multispectral sensing and imaging applications with potential combinations including UV and visible bands on a common Si sensor. In addition to customized coatings, the optics are delivered in the form to fit your application in specific substrates, shapes, and sizes.

The UV range extends from 200 400nm, below human vision and in the responsivity of UV-optimized silicon detectors. Many applications have valuable spectral signatures in the UV region that can be evaluated using precisely positioned bandpass filters.

PIXELTEQs ultraviolet (UV) optical bandpass filters deliver precise transmission of specific UV spectral bands while blocking out-of-band signals at higher and lower wavelengths. The multi-edge bandpass filters transmit wavelengths defined by a nominal center wavelength (CWL) and bandwidth (FWHM – Full Width Half Max) while reflecting both shorter and longer wavelengths. Also known as thin film or interference filters, PIXELTEQs bandpass filters use multi-layer hard coatings that provide durable performance without fading or aging in high output luminaires.
