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.
