A step tablet is a pattern in which transmittance or reflectance changes in discrete steps. It is used for adjusting exposure machines, evaluating photosensitive material properties, and for testing scanners and image sensors. Transmittance and reflectance, the number of steps, and the arrangement can be customized to order. We can measure and submit the reflectance density and transmittance of the product.
Examples of production using Glass Substrate
The step tablet with a glass substrate that we offer creates step changes in transmittance by controlling the thickness of the metal film. The transmittance, number of steps, pattern size, and outer diameter of the glass can be selected according to the intended use. The metal film offers the advantage of high durability against humidity and light exposure. Additionally, the pattern can also be created with a dot gradation.
This is a transmissive step tablet with a gradual change in transmittance in concentric circles. The pattern is made of a metal film.
Example of production using PET Substrate
This is a transmissive step tablet with a film substrate.
Example of production using Photographic Paper Substrate
This is a color reflective step tablet. In addition to the gradual changes in the red, blue, green, and black patch shapes, it also incorporates solid patterns inspired by skin tones.
