Page 16: Safety Labels
Features Safety labels An SuperK Fiber Delivery (FD) system includes labels that indicate hazards and safety and product information. An FD includes the following labels types: • Input power level warning • FD type and wavelength coverage • Laser aperture labels with serial number on backside Laser Aperture A laser aperture label is tagged on the fiber cable. -
Page 17: Installation
The input power to the fiber delivery system (FDS) should always be lim- ited to below 500 mW. Note: Ensure to select the correct SuperK CONNECT model (VIS or IR) that match- es with your accessory output port. To mount a SuperK CONNECT to a laser accessory, follow the steps in Procedure 1 below. -

Lock screw Note: The lock screw may be mounted on either side of the SuperK CONNECT. If you cannot access the screw, unfasten and remove the lock screw assembly and install it on the opposite side of the CONNECT. You may need to remove the CON- NECT from its mounting location to gain access. - Page 20 Mounting the CONNECT...

Page 21: Optical Alignment
Warning: The SuperK CONNECT together with a SuperK laser system constitutes a class 4 laser source and must be regarded as a potential hazard to the operator. Make sure to wear laser protective eyewear when operating the SuperK CON- NECT and when aligning its optical output. -

10. Repeat step 8 adjusting the thumbscrew pairs iteratively until the optimum alignment has been achieved when no further power increase can be realized. 11. The SuperK CONNECT is now aligned with the FD. Note: When using a power meter to measure the light from the FD connector, it is recommended to use a sensor with a fast response time. -

Tips for steering the beam path out, tightens (improves) the accuracy of the alignment spot. This is because, the pin hole physically limits the angle of acceptance, which decreases the further the pinhole is away from the mirror - see Figure 16 below. -

In these cases, you must use the thumbscrews to move the beam slightly, positioning the beam onto the fiber facet.

Page 31: Notes On Fiber Delivery
Notes on Fiber Delivery NKT Photonics can supply multiple Fiber Delivery types which can be characterized by their fiber and connector types. This chapter includes information discussing fiber types, coupler and collimator keying, mating fibers, cleaning fiber facets and protecting them from contaminants. -
Page 32: Pm Fibers And Keying
PM Fibers and keying diverging field. The wide divergence means that a standard butt joint cannot be used with subsequent fiber delivery systems due to the coupling loss. Therefore PCF is only suitable when the FD is fitted with an output collimator which can adequately refocus the light with its achromatic lens. -
Page 33: Cleaning Of Fiber Facets
Fiber and connector care Cleaning of fiber facets The fiber connector on the FD may occasionally require some cleaning of the fiber tip. Before making any fiber connections, always inspect the fiber facet of all connectors using an inspection scope. A scope with both coaxial and oblique illumination is useful in exposing any contaminants or defects in the facet. - Page 34 Fiber and connector care...
