Translucent test chart

It is the ideal tool for evaluating optical devices. We customize it according to measurement specifications such as resolution, positional accuracy, and gradient patterns.

The "Test Chart" is the ideal tool for evaluating the performance of optical devices. The transmission type is based on transparent glass or PET. The "Transmission Glass Chart" is a product that forms high-precision, high-resolution patterns using a chromium thin film on a transparent glass substrate. The pattern shapes typically include various line widths and spacings arranged regularly to check resolution, as well as dot patterns and crosses arranged in an array. The "Transmission Film Chart" features black patterns drawn on PET material. The size of the patterns can be as small as a minimum line width of 20 micrometers. It is characterized by the ability to create large-sized products. Additionally, Equa also performs precise outer diameter processing. Furthermore, color charts using glass or PET substrates can also be created. 【Product Lineup】 ■ Resolution Chart ■ Calibration Chart ■ Gradient Chart ■ Step Tablet ■ Glass Scale ■ Grid Chart *For more details, please download the catalog or contact us.
