Calibration board diagrams
CGB-020
Note: CGB calibration boards are made of carbon fiber material and designed in an integrated method, so they do not require additional adapters.
CGB-035, CGB-050
Note: The difference between CGB-020 and CGB-035/050 lies in mounting hole arrangements:
CGB-020 has one type, while CGB-035/050 has another.
OCB calibration boards
Note: OCB calibration boards are made of glass material, have no mounting holes, and are intended solely for EIH calibration.
BDB calibration boards
Note: BDB calibration boards have acrylic surfaces and metal adapters.
Diagrams of calibration circles arrangement and spacing
CGB calibration boards
A CGB calibration board has 5 rows and 4 columns of calibration circles, arranged asymmetrically.
BDB calibration boards
Similar to CGB calibration boards, a BDB calibration board also has 5 rows and 4 columns of calibration circles, arranged asymmetrically.
OCB calibration boards
An OCB calibration board has 11 rows and 9 columns of calibration circles, arranged symmetrically.
