AXIOM Gamma

1 Optical Modules

1.1 Lens Mount Module (LMM)

1.2 Optical Filter Module (OFM)

Optional.

1.3 Image Sensor Module (ISM)

The image sensor in the AXIOM Gamma will be mechanically adjustable in dimensions of flange focal distance (back focus = Z-axis), a shift in XY-axes and XYZ rotation.

For creating space for the heatpipes and decoupling the image sensor from the rest of the module two rigid-flex PCBs are added to the existing designs. The rigid part of the rigid-flex PCB will be screwed to the back of the module exposing the connectors to the back.

2 cooling options:

passive: Copper heatpipes
active: Peltier element behind sensor (see below)

Peltier:

Usage of a Peltier-element proves to be problematic:

High power consumption renders mobile usages inefficient

Power consumption within the Peltier generates more additional heat

Water condensation within the electronics on the cool Peltier side, requirement of sealing -> increased complexity of manufacturing, design, maintenance, repairs, etc.

Conclusion:

Sensor front end module without Peltier element for general usage, one version with Peltier element for people who are aware of the implications and/or for experimentation purposes
