Optical assemblies

An optical assembly combines geometry, alignment and the properties of its materials.

Prepare

Establishing a reference

Focal length describes the optical power of a lens.

Describing the setup

Aperture limits the bundle of light entering a system.

Reading the first observation

Alignment changes should be recorded consistently.

Working with variation

Aperture limits the bundle of light entering a system.

Comparing the records

Alignment changes should be recorded consistently.

Interpreting a diagram

Reflections depend on angle and surface treatment.

Recording the conditions

Alignment changes should be recorded consistently.

Reviewing the method

Reflections depend on angle and surface treatment.

A second pass
