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.
Each sensing head is built from a single-mode fiber; a miniature collimating lens is integrated into the fiber to achieve millimeter-scale sensor dimensions.
The modules are cylindrical with an optional 25 mm mounting flange and consist of an aluminum housing, laser diode, drive circuit and collimating lens. The mechanical dimensions are a 12 mm diameter x 43 mm length.
The housing holds a self-contained diode laser package with a built-in collimating lens to shape the beam.

The modules consist of an anodized aluminum housing, laser diode, drive circuit and collimating lens, either cylindrical or with a 25 mm mounting flange.
A special collimating lens captures, then focuses the light from the LEDs to the fiber optic panel.
