Product description
Narrow band filter is a kind of Optical Filters, which can separate out the monochromatic light of a band, allows optical signal through specific waveband, nevertheless the light signals from both sides of the waveband are blocked. The band of narrow bandpass filter is relatively narrow, it is generally less than 5% of the central wavelength.
Narrow-band pass filters main function is to make the passage of light of a specific wavelength, let the other wavelengths of the light reflection (or attenuation) of optical components. Half wave width is usually controlled in 20nm or smaller, ultraviolet, visible light, near infrared wavelength, far infrared wave band. My company's narrow band filter using multilayer epidural by ion assisted deposition of nanometer materials and high vacuum evaporation coating, good compactness, high imaging definition. Besides narrow band pass filter, Coupletech also provides all kinds of Optical Elements, Optical Lenses, Optical Windows, Optical Mirrors, Optical Prisms.
We also provide 365nm,380nm,394nm,405nm,420nm, 430nm, 440nm, 450nm,465nm, 470nm, 490nm, 520nm, 532nm , 546nm , 550nm,560nm, 570nm, 580nm, 590nm, 600nm, 620nm, 635nm, 648nm,654nm, 660nm, 670nm, 690nm, 720nm, 740nm, 760nm, 780nm, 808nm 810nm, , 830nm, 845nm, 850nm, 860nm, 870nm, 880nm, 905nm, 940nm, 980nm, 1000nm,1050nm, 1064nm, 1080nm narrow band filter.
