Neutral Density Filters

BioPhotonics
Jan/Feb 2026 NX Series neutral density filters from Midwest Optical Systems are for broadband light control across the visible, NIR, and SWIR spectrums. Developed for CMOS, indium gallium arsenide, and carbon quantum dot technology, the optics are ideal for machine vision, inspection, surveillance, and scientific imaging, and applications requiring longer exposure times, reduced depth of field, and/or precise illumination control. The filters feature transmission options of 6.25%, 12.5%, 25%, and 50%. Custom formats are available with sizes up to 165 nm² in 1-mm or 2-mm thickness. More products
