Bandpass filters allow light waves to pass through and block other interfering light.
The types of bandpass filters produced by Nano Macro Optics Co.,Ltd. (NMOT) include laser filters, filters for biochemical analysis, CCD/COMS digital imaging and detection filters, which are widely used in lasers, laser ranging, laser scanning, laser night vision, license plate recognition, car four-wheel aligner, face, iris recognition, security camera, somatosensory games and machine vision and other high-tech optoelectronic integration.
The bandpass filter adopts IAD ion-assisted coating technology to improve the compactness of the film layer, reduce the wavelength drift caused by changes in the external environment, and has the characteristics of excellent imaging quality and long service life, ensuring wide cut-off range, cut-off depth and high light transmittance.
