Broad Bandpass Filters

A long pass filter and a short pass filter fastened together to create a variable bandpass filter with an bandwidth from 20nm to 100nm. The center wavelength allows to be adjusted by combining different long pass filter and short pass filters.

Day and Night Filters

Day and Night filters pass the visible and 850nm of wavelength but cut off the NIR region from 950nm-1100nm. The filters are used in CCD or CMOS imaging system to produce a true color image. This filter allows the imager to work both at day and night. The application areas concern the secure monitoring, digital camera, visual telephone, visual doorbell, digital telescope and visual check-in recorder etc.

Isolation Edge Filters

The isolation edge filter is to cut off the visible and pass the 850nm or 940nm of wavelength. The function of such edge filter isolates the objects and detector. The viewer can not discover the detector by naked eyes.
