# Requirements To integrate the Zeiss Axio Observer 7 or .Z1 with the CODEX instrument and run CODEX experiments, the following minimum hardware and software requirements need to be met. Consult with your Zeiss representative for the final design and the most up-to-date components. ## Software CODEX system requires ZEN Blue **2.3, 2.5,** or **2.6**. The following software modules are required for CODEX : * ZEN Module Z Stack (PN 410136-1030-110) * ZEN Module Tiles (PN 410136-1025-110) * ZEN Module Autofocus (PN 410136-1028-110) ## Hardware | **Component** | **Zeiss Axio Observer 7 / .Z1** | | ------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | | **Stage** |

• Scanning Stage (PN 432029-9904-000)

• Piezo Stage (PN 432027-9001-000)

| | **Camera** |

• Photometrics Prime BSI

• Orca-Flash4.0 V3

Useable but not preferred:

Axiocam 506 mono (4.5um per pixel is lower than our recommendation. QE low for Cy5 and too low for optimal AF750 signal)

| | **Objectives** |

Plan Apochromat 20x Zeiss

• (PN 420650-9901-000) Older model/Discontinued

• (PN 420650-9902-000) Latest version

Check with your Zeissrepresentative to confirm the specific Filter cubes or Filter LED. The information on the dye sets used for CODEX can be found [here](https://help.codex.bio/codex/cim/microscope-specific-settings/microscopes#dye-set-and-filter-cube-configuration) | **Light Source Options** | **Corresponding Filter Sets** | | ----------------------------------------------------------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | | **Illuminator HXP 120V** |
