OCTP Series Scanner Chapter 3: Components and Compatibility

3.1.1. Fiber Collimation Module

Figure 2 Fiber Collimation Module with Built-In Fiber Collimator
The fiber collimation module has a built-in fiber collimator with 25 mm focal length. The 2.0 mm narrow key
FC/APC receptacle is centered within a kinematic mirror mount, which adapts the fiber port to our 30 mm cage
system.
The cage compatible design enables the use of different beam diameters and collimator focal lengths, although
the clear aperture of the scanner set is limited to Ø6 mm.

3.1.2. Optical Beamsplitter Module (not for OCTP-NR)

Figure 3 Optical Beam Splitter Module
The optical beamsplitter module consists of a non-polarizing cube beamsplitter that is mounted inside a 30 mm
cage cube. This cage cube is secured to a lockable rotation mount. The cube beamsplitter's length, width, and
height are 20 mm.
The 30 mm cage cube has four ports, one of which is blocked by an end cap before being shipped. In principle,
it is possible to use this last port for asymmetric light coupling, a second detector, or a second input wavelength.
Please contact Thorlabs' OCT support (see Chapter 11) for details.
