Visible Bandpass Filter

PIXELTEQs optical bandpass filters deliver precise transmission of specific visible spectral bands while blocking out-of-band signals at higher and lower wavelengths. The multi-edge bandpass filter design transmits both shorter blue and longer red visible wavelengths and reflects central green visible 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.

Visible light extends from 400-700nm, within the normal responsivity of cost-effective silicon (Si) detectors. Many applications have valuable spectral signatures that can be differentiated and evaluated using precise narrow-band visible bandpass filters.

Dichroic Bandpass Filters vs. Absorption Filters

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.

OEM Custom Options

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 applicaitons. In addition to customized coatings, the optics are delivered in the form to fit your application in specific substrates, shapes, and sizes.

Integrated Solutions

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:

  • Excitation filters: condition broadband illumination for selective narrowband excitation channels
  • Emission filters: bandpass filters around narrowband emission wavelengths to improve contrast and signal-to-noise ratio
  • Dichroic beamsplitters: separate emission wavelengths (reflection) from fluorescence wavelengths (transmission)
  • Anti-reflective coatings: maximize transmission by reducing reflections due to index of refraction deltas
  • Patterned Bandpass Filters: pixel-scale filter arrays on active devices for application-specific photodiodes and imagers
  • Machine vision
  • OEM sensing & imaging
  • Biomedical fluorescence
