Visible 300 - 700nm Narrow Bandpass Filters
Visible narrow bandpass filters are optical filters designed to transmit a specific range of wavelengths while blocking out unwanted wavelengths. These filters are essential in various applications where precise control over the light spectrum is required. More on the uses and applications of visible narrow bandpass filters as well case study examples of filters we have manufactured can be found below.
We design and manufacture custom visible narrow bandpass filters between 300 nanometres to 700 nanometres to any custom specification. We hold a wide range of stock substrates such as Glass, Sapphire, Quartz, Calcium Fluoride and more. We also have onsite dicing, so we are able to design, manufacture and dice filters to their finished size with lead times as little as 2 weeks.

Applications
Machine Vision and Robotics:
Narrow bandpass filters are integrated into machine vision systems for industrial automation, quality control, and object recognition applications that require precise sensing and analysis of visible light wavelengths.
Photography and Imaging:
In photography, narrow bandpass filters are used to enhance colour contrast, reduce unwanted reflections, and improve image quality by selectively filtering specific wavelengths of light within the visible spectrum.
Spectroscopy and Analytical Instruments:
Narrow bandpass filters are utilized in spectroscopy instruments for analysing atomic and molecular emissions, fluorescence, and absorption spectra in scientific research, chemical analysis, and material characterization applications.
Fluorescence Microscopy:
In fluorescence microscopy, narrow bandpass filters are essential for isolating specific fluorophores and dyes that emit light within the visible spectrum, enabling researchers to visualize and study biological samples with high sensitivity and resolution.
Optical Communications:
Narrow bandpass filters play a crucial role in optical communications systems for wavelength division multiplexing (WDM) applications, where they enable the transmission and reception of multiple optical signals within the visible spectrum range.
Security and Surveillance:
In security systems and surveillance cameras, narrow bandpass filters are used for facial recognition, license plate recognition, and object tracking based on visible light imaging and analysis.
Colourimetry and Colour Matching:
Narrow bandpass filters are used in colorimetry applications for colour measurement, colour matching, and quality control in industries such as printing, textiles, and graphic design ad well as art projects to determine colour pigments to restore pieces of artwork.
