NVIS Filter and Affordable NVIS Compatible Display
ALP developed coating processes that would produce different classes of IR-cut off filters, NVIS filters, suitable for NVIS compatible applications. We can also make filters with customized IR cut-off specifications. Please call us for details.
A 6.4" LG LCD was installed with our NVIS filtered high bright LED backlight, integrated with our iMesh and gTouch. The display shows very little greenish color tone to the unaided eyes. The picture on the right was taken through night vision goggles. It is clear that the light from the screen of the treated 6.4" unit was successfully blocked and appeared invisible through NVIS goggle.
ALP offers various NVIS filters and NVIS compatible products. A nvisTouch (or nvisFilter) that is laminated with such a IR cut glass may be conveniently overlaid on top of a display to achieve a high level of NVIS compatible DHA. These IR-cut filters may also be cut to the size and installed in a LCD backlight strip.
