Filter type EPD detects variation of specific light distributed
by the band-pass filter.
It can be applied to where;
- output signal is small
- there are a lot of background noise
- target wavelength is fixed
- High resolution
- Analog signal output, 0~10VDC
- Gain/ Offset adjustable
- Target wavelength selectable
- Best performance, with low price-
