The print paper chart is a reflective test chart made using black and white photographic paper, which is a photosensitive material. Equa's print paper chart comes in two types: a high-definition monochrome type that pursues fine line representation, and a gray type that takes advantage of the intermediate color representation unique to print paper. The former is used for calibration purposes of various optical products, resolution charts, distortion charts, and more. Typically, a film master is created first, and the print paper chart is produced based on that. It is drawn using a high-precision parallel light source exposure machine in a clean room managed at 23 degrees Celsius and 50% humidity. The unique exposure process reproduces the highest level of sharp pattern edges. Patterns can be created with a minimum line width of 30 micrometers. The latter is used for creating products for color management of scanners and optical devices. A pattern featuring step tablets and solid patches is representative. Reflective density, number of steps, and arrangement can be customized. The product can measure reflective density and is also compatible with the creation of color products. *For more details, please download the catalog or contact us.*

The "White Glass Chart" is a product that forms a pattern with a metal film on white glass (Neoceram N11, Nextreama). It is effective for measurement and positioning evaluation using reflected light. The substrate can be selected in two types: mirror and non-mirror (matte). The pattern line width can accommodate a minimum of 2um. The "White PET Chart" features a black chart pattern precisely drawn on a flexible white PET material. Compared to paper-based photographic paper products, it offers superior durability. The maximum size is A3. The "Photographic Paper Chart" is a reflective test chart created using black-and-white photographic paper, which is a photosensitive material. It is used for calibration purposes of various scanners and as a resolution chart for camera photography. It is characterized by a subdued texture compared to products made from glass or PET substrates. Additionally, there are high-definition charts with a white background for transmission-type glass and film charts, as well as reflective color products. The patterns can be freely customized to match measurement specifications. *For more details, please download the catalog or contact us.*

• Evaluation Board

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.

• Evaluation Board

A photomask is a master plate used for exposing patterns onto wafers, glass substrates, printed circuit boards, metal plates, and other materials in the production of electronic circuits, display devices, optical components, and precision machinery. The patterns drawn on photomasks are used in many electronic products, semiconductors, televisions, smartphones, noise filters, scales, and network-related products. The photomasks provided by Equa are primarily drawn using the latest equipment that uses lasers as the light source. Equa creates data from drawings to support the realization of customers' images and concepts. 【Features】 - Master plate for exposure - Drawn using the latest equipment with lasers as the light source - Accommodates diverse needs - Patterns for circuit boards and optical components designed using CAD - Types of substrates: Two types of glass substrates: soda-lime and synthetic quartz, and the film is PET For more details, please contact us or download the catalog.
