Technical FAQ

Configuration questions for Spatial Light Modulator

Which fiber and connector does the Spatial Light Modulator use?

Data interface: Mini DP. Specify connector polish and fiber architecture together. FC/PC, FC/APC and SMA interfaces, and single-mode, multimode and polarization-maintaining fibers, impose different return-loss, mode-field and alignment requirements.

How should the Spatial Light Modulator be included in an optical power budget?

Spectral range: 420nm-820nm. Check the Laser components and accessories passband, insertion loss, return loss and power handling at the actual source wavelength; a nominal telecom-band label is not a substitute for the configured range.

Does the Spatial Light Modulator require a controller?

Enter the power supply: 5V 2A. Match supply voltage, analog or digital command range, connector pinout and default optical state to the instrument interlock. Confirm the unpowered state explicitly — it decides what happens to the link on a power failure.
