Optical Train and Thermal Review
We review tube diameter, length, wall concept, internal clearance, and optical-axis references in the context of research, observatory, and advanced amateur optical systems. The same review records thermal cycling, dew, outdoor exposure, handling, and the optical alignment strategy and any customer-controlled acceptance criteria.
- Define tube diameter, length, wall concept, internal clearance, and optical-axis references
- Record thermal cycling, dew, outdoor exposure, handling, and the optical alignment strategy
