A LP610 filter is suitable when using a monochorome camera and the intention is to pass both red and near infrared wavelength light. When red LED lighting is used, in most cases a BP635 or BP660 Bandpass filter will be more beneficial. In either of these cases, longer infrared wavelengths generally can have a negative effect on contrast. These filters have also seen use in single camera NDVI imaging applications as an alternative to “Wratten 25 or 25A” filters. However for such uses we would instead recommend our DB660/850 as a far superior alternative.
