Filters play a very important role in machine vision system. There are several categories according to their characteristics:
1. Bandpass Filters: the main specs are CWL (center wavelength), FWHM(full width at half maximum), narrow bandpass filter: <30nm, wide bandpass filter>60nm.
2. Cut-off filter: short pass filter & long pass filter.
3. Dichroic filter: pass a small range of colors of light, and reflect other colors.
4. Neutral Density Filters: absorb or reflect the part of light that is not transmitted.
5. Fluorescence Filters: mainly used in medical application for sorting or selection.
6. Astronomy Filters: improve the image performance when taking astronomical pictures.
Our filters have high cost performance, high quality, and quick lead time features.
