1810nm bandpass filter
PRODUCT CATEGORIES
1810nm bandpass filter is a kind of near-infrared filter. At present, it is widely used in near-infrared moisture meter, laser equipment and medical equipment. The working principle of near-infrared moisture meter is KIBEL Lambert law, that is, there is a certain relationship between the intensity of light reflected by solid materials and the moisture concentration in solid materials. The energy absorbed by water molecules increases with the increase of moisture concentration
