Step Tablets are a type of pattern that changes transmittance or reflectance in stages.
It is used for adjusting exposure machines, evaluating the characteristics of photosensitive materials, and evaluating scanners and image sensors. Transmittance and reflectance, number of stages, and arrangement can be customized to order. The product can measure reflection density and transmittance.
Examples of production using Glass Substrate
This is a rotating gradation. The gradation is expressed with a thin chrome film on the glass substrate. The shading of the gradation is made up of the placement ratio of dots with a minimum size of 2um.
This is a transparent step tablet where the gradual change in transmittance is in concentric circles. The pattern is a metal film.
Example of production using PET Substrate
This is a transparent step tablet based on PET.
Example of production using Photographic Paper Substrate
This is a colored reflective step tablet. In addition to the gradual changes in the patch shape of red, blue, green, and black, it also combines a solid pattern that resembles the color of the skin. The material used is photographic paper.
