OPTICAL FILTERS WHITE PAPERS AND CASE STUDIES
OPTICAL FILTERS PRODUCTS
Optical filters enhance system precision by selectively transmitting or blocking wavelengths, supporting machine vision, spectroscopy, fluorescence microscopy, and medical imaging with customizable solutions.
ODiate Fluorescence Filter Sets are designed to meet the demanding requirements of fluorescence and microscopy applications.
SWIR filters, which transmit short-wave infrared light, reveal invisible details like overpainted scenes in paintings or bruises on fruit.
Explore new capabilities extend finished optics wavelength range from mid-UV to longwave infrared.
Semrock optical filters combine ion-beam-sputtering systems with our deposition control technology, unique predictive algorithms, and volume manufacturing for unsurpassed, standard-setting performance.
Precision XY Saw Cutting offers high-volume, small-part fabrication with tight tolerances, ideal for optical components requiring precise dimensions and low defects.
Edge Blackening is the application of a matte black paint to the edges of an optical filter to prevent stray light inside the filter from re-entering the light path outside the filter.
Transform your optical systems with Semrock filters - the brightest, most durable, and spectrally sophisticated filters in the market.
