Module 1:
The post-doc’s tale
Course 2 of Optical Engineering: Optical efficiency and resolution
with Dr.
Robert R. McLeod and Dr. Amy C. Sullivan
The post-doc’s (sad) tale
Fiber bundle
from spectrometer
Diameter D
divergence θ
?
Optics
?
Instrument slit of
height h and length L
In this case ! θ ≈ 10 ℎ ℎ⁄(
Fiber bundle
to spectrometer
Optics
so the maximum efficiency is ~1/10
…no mater WHAT optics you try.
