CHROMAFILTER® VFD Filters
   
PCI offers more than 20 different colours of Chromafilters for Vacuum Fluorescent Displays. Our Chromafilter VFD filters are used to provide optimum readability and contrast enhancement of your VFD’s. The filter’s light transmittance can be adapted to emit light in combination with your VF display in your choice of colours! You can create a high degree of contrast by choosing either a filter with a narrow transmittance curve or a dark tinted filter. The latter will make information from the display stand out clearly against dark backgrounds. This may increase readability and at the same time provide an elegant design function.
 
Technical Data
Thickness from 0.5 mm. Tolerance down to +/- 0.1 mm.
Dimensions up to 1500 x 1000 mm. UV block up to 400 nm
 
Chromafilter ND Filters
Neutral Density Filters (ND Filters) are for evaluation purposes only. Use the filters in front of VF Display + selected Colour Conversion Filter to simulate a two-layer solution. In a typical two-layer solution the Chromafilter ND filter is a 3D shaped, injection moulded cover glass.
