Alcon Accurus Medical Lightsource Adapter

This is a model of an adapter for the Alcon Accurus Medical Lightsource. It has a 1.5mm bore to integrate lightguides. Download and edit the .step file to modify the dimensions. 

Collimator Adapter

The second iteration of this adapter contains a spherical lens combined with a collimator to focus the wide emitted lightbeam into small-diameter lightguides via a SMA905 optical connector. Use M3 heat inserts to clamp down the spherical lens and connect the adapter to the collimator. Here are the components used in this configuration:
 

• Optical light guide: https://www.edmundoptics.de/p/762mm-high-resolution-image-conduit-with-24mum-fibers/10843/
• Spherical lens: https://www.edmundoptics.de/p/100mm-diameter-n-bk7-ball-lens/2569/ 
• Collimator (SMA connector): https://www.edmundoptics.de/p/543nm-alignment-040-na-fiber-collimator-w-sma-connector/19443/
• SMA-905 connectors: https://www.thorlabs.com/newgrouppage9.cfm?objectgroup_id=1383 

Disclaimer - Danger due to high temperatures!!

This is not an official Alcon model. I measured the connector myself and replicated it in CAD for research purposes. I strongly recommend that you do NOT use regular 3D printing filament to manufacture this adapter. I recommend using some kind of metal like Aluminium or Stainless steel, or a high-temperature polymer. Please be careful when using acylic lightguides with the your lightsource, as they might melt.
