Optical assemblies

Comparing results / Optical assemblies

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

01. Establishing a reference

An optical assembly combines geometry, alignment and the properties of its materials. Focal length describes the optical power of a lens. A useful working note records the context and the purpose of the study. Keep the details that explain what was noticed, and distinguish them from ideas that emerged later.

Focal length describes the optical power of a lens. This point should be read together with the stated reference and the conditions of the record.

02. Describing the setup

Aperture limits the bundle of light entering a system. When revisiting a series of observations, begin with the original context. Record the order of the work and keep the first descriptions alongside any later interpretation.

Aperture limits the bundle of light entering a system. This point should be read together with the stated reference and the conditions of the record.

03. Reading the first observation

The next pass through optical assemblies focuses on comparison. Alignment changes should be recorded consistently. Look for the relationships between the details and retain enough context for another reader to understand the study.

Alignment changes should be recorded consistently. This point should be read together with the stated reference and the conditions of the record.

04. Working with variation

Reflections depend on angle and surface treatment. This point should be read together with the stated reference and the conditions of the record.
