Optical aberrations in the collimating lens mechanism can degrade the quality of OCT images first by introducing imperfections to the collimated beam in the forward path, which can increase the sample spot size, and second by reducing the coupling efficiency to the fiber, which decreases the signal-to-noise ratio (SNR) in OCT images.
Therefore, the fiber and collimating lens should be aligned very carefully.
The housing holds a self-contained diode laser package with a built-in collimating lens to shape the beam.
