The next few articles will focus on helping you weight the importance of each characteristics of the optics you need for your application.
This is critical when building an optical system. For instance bad flatness will introduce wavefront deformation which will limit the quality of the image and surface irregularities will lower the damage threshold of the system.
When choosing an optic, one must consider the following specifications:
- optical substrate
- coating type and damage threshold
- usable wavelength range
- optic size and clear aperture
- surface figure or flatness
- surface quality
