Traditionally, for inspection of defective pixels in LCDs, ND filters for camera lenses had been used. However, those filters had to be layered according to the transmittance required and many users requested filters designed exclusively for LCD inspection. To meet such requests, we now offer 8 types of the ND-LCD series filters, each having different transmittance values, enabling precise detection of defective pixels and distorted images which can be achieved only by the filters developed for LCD inspection. The ND filters for LCD inspection with high reliability and durability have now become available by application of Fujifilm’s high precision technologies gained through experience in the development of a variety of camera lens filters.

For the ND-LCD series filters, triacetylcellulose (TAC), which can be used as a LCD material because of its optical characteristic, is used for the substrate. TAC produced by Fujifilm’s excellent proprietary technologies is thin and light, and in addition, it has an outstandingly strong surface.
The high-purity organic dye realizes exceptional resist-ance to light and heat.
For the packing case, synthetic paper with a high moisture resistance is used for the long-term preservation and main-tenance of the flatness of filters.
The attached protective cardboard can be used as a mount suitable for the LCD inspection.
