440nm bandpass filter
PRODUCT CATEGORIES
440nm bandpass filter is a kind of optical device with narrow bandwidth, which can let the light of specific wave band pass through and cut off or reflect the other short wave band The band-pass filter of our company is made of multi-layer dura ion assisted deposition nano materials by high vacuum evaporation. The film has good compactness and high imaging definition.
