3.1.4. OCT Scan Cube Module
Figure 5 OCT Scan Cube Module
The OCT scan cube module provides high-speed, two-dimensional (X and Y) raster scans of the specimen. The
clear aperture of the scan mirrors used within is Ø6 mm. The module also contains a high-resolution video
camera for recording the sample during the measurement.
The electrical control interface hosts the included Thorlabs electric control cable to connect the imaging scanner
with a Thorlabs OCT base unit. Please contact Thorlabs’ OCT support (see Chapter 11) for information
regarding the pin configuration.
Should the user wish to view the direct, non-descanned output of the objective (i.e., by passing the primary
scan mirror, transmitting the visual wavelength range), the top of the scan cube contains an output port with a
removable end cap (Item # SM1CP2). This port can be used for different imaging modalities or additional
sample illumination. Unscrewing the end cap exposes an internal SM1 (1.035"-40) threading, which is
surrounded by four 4-40 taps that are compatible with our 30 mm cage systems.
A transmission graph of this scan mirror is given in Figure 35.
ATTENTION
Use of the direct output port requires removal of the camera. In addition, a hot mirror with a 2.5 mm
circular aperture could be removed. Please contact Thorlabs’ OCT support (see Chapter 11) for details.
