Description
Optical Filters from X-Z LAB provide precise control over which wavelengths reach your sensor, detector, or eye. The lineup spans colored optical glass, light and color filters, color filtering lenses, insulating glass, quartz glass, infrared penetrating glass, near-infrared penetrating glass, UV glass, black UV penetrating glass, ND glass, orange, green and yellow glass, and band-pass filters, plus specialty filters for currency-counting machines.
Optical Filters for every wavelength band
Each filter type serves a distinct job. Colored glass and light filters tune color balance and contrast in photographic equipment and optical devices. UV glass and black UV glass support UV analyzers and inspection setups. Infrared and near-infrared penetrating glass serve thermal and night-vision applications. ND glass cuts intensity without shifting color. Band-pass filters isolate the exact spectral line that meters and instruments need to see.
Band-pass designs transmit one narrow region and block the rest, which suits fluorescence readers and laser-line cleanup. Long-pass and short-pass styles split the spectrum at a single edge, a simple approach for color filtering lenses and projector optics. Neutral-density glass attenuates the whole band evenly and protects sensitive detectors from saturation.
Applications of Optical Filters
Many systems rely on this kind of spectral control: photographic equipment, meters and instruments, and optical devices. Medical treatment apparatus, teaching equipment, and projectors use it too. The range also covers UV analyzers and financial equipment such as currency counters. It also serves airport lamps and technological research institutes.
How to choose the right filter
Start with the wavelength band you need to pass or block. Then check the substrate. Quartz glass suits UV work, while infrared penetrating glass suits thermal bands. Standard colored glass covers most visible-light tasks. Confirm size, thickness, and surface quality against your mechanical mount. Decide whether you need a coated or uncoated surface — coatings sharpen the cut-on and cut-off edges for demanding instruments.
Tell us your wavelength range, size, and substrate, and we will match the right filter to your system. You can also pair them with our Optical Windows to protect the full optical train. Request a quote.
