White Glass Charts
The chart is formed by metal film on the Neoceram N-11 or Nextreamer, color is white, and it’s applicable for calibration, positioning measurement and pattern evaluations with the use of reflected light. User can select specular or non-specular (mat finish) type. Coefficient thermal expansion is 1.3 x 10-6. Material film is mainly formed by double layers consists of chrome and chrome oxide, and the color is golden brown or deep navy blue. We can supply high precision chart made by a professional method. Chart size is up to 430 x 430 mm, and minimum size feature is 2 μm.
Film Charts with White Backside
White PET Film Charts
It is a chart that drawn a black pattern with high precision on a white flexible PET material. It has superior durability compared to conventional paper-based chart. It also allows for the formation of fine patterns, achieving a ladder pattern with a resolution of at least 20μm. Sizes include A4 and A3. PET thickness can be selected from 125μm, 188μm, etc. If you are using it as a chart for photography, we offer a product bonded to an aluminum composite panel.
Photographic Paper Charts
Photographic paper, which is a photographic-sensitized material, features high resolution in comparison to offset printing. Despite having a thin paper base, this paper is capable of ladder patterns of as low as 50 um. Photographic paper charts are produced by copying a film master, but if precise positional accuracy is required, use of a glass master is recommended. For cases in which these are to be used as charts for photography, we offer products in which Photographic paper is affixed to an aluminum composite plate.
Aluminum Substrate Charts
This is a test chart with a black precision pattern formed on an aluminum substrate.
Metal charts are suitable for applications that require use in harsh environments, such as outdoor exposure, abrasion resistance, and temperature resistance. Also, unlike glass, there is no risk of it breaking, making it easy to handle. The substrate surface has a fine matte finish, so there is no reflection on the camera.
