The narrow-band filter is subdivided from the band-pass filter and has the same definition as the band-pass filter, that is, the filter allows the light signal to pass through in a specific band, and deviates from this band. The optical signals on both sides are blocked, and the passband of the narrowband filter is relatively narrow, generally less than 5% of the center wavelength value.
The main parameters are: center wavelength, full width at half maximum (bandwidth), peak transmittance, cutoff range, cutoff depth (OD value) Center wavelength: The center wavelength of a narrowband filter is generally the operating wavelength of the instrument or device. It refers to the wavelength at the center of the passband. Half-height width (bandwidth): Bandwidth is the distance between two locations where the transmission in the passband is half of the peak transmittance. Cut-off depth (OD value): The cut-off depth is the maximum transmittance of the cut-off band that allows light to pass through.
Precautions:
1. Avoid storing the filter in a humid, high temperature environment; 2. Avoid hard objects scratching the surface of the filter and crushing the weight; 3. Note that the surface of the filter should not be dusty. If it is stained with dust, please gently wipe it with a mirror paper; 4. The temperature of the filter should not exceed 80 degrees. If it needs to be used under high temperature conditions, please explain to the seller that it can only be used at high temperature after tempering, but it is best not to exceed 250 degrees to avoid damage to the filter; 5. During the use of the filter, avoid sudden rise and fall of the temperature. If the temperature difference is too large, the filter will be broken. Please be careful.
