© 1999 - 2000 CLP date: 23. September 1999
1.)LEGEND: The hybrid construction of fiberoptic systems has first been developed in 1992 at SCHOTT company by Dr. Wodrich. Since then this versatile construction has become world wide accepted and spread with its mechanical standards. CLP has developed a complete line of fiberoptic components and complete systems matched to this standard.
2.) ADVANTAGE: The hybrid collimator construction is an interchangeable part of the fiberoptic delivery system, and allows to optimize your delivery system for your special application. (lasersource, divergency, beamdiameter etc.) Another key feature is, that the fiber can be kept connected to the collimator, as the collimator itself is a key locked plug and play unit to the launcher and the flange adapter on your projector, with excellent repeatability. This results in a permanent hermetical sealed operation of your sensitiv fibertip eleminating possible contamination during connection procedures in the field.
3.)THE COLLIMATOR: The precise machined cylindrical housing is assembled with an achromatic lense of highest world standard and a Z-adjustable SMA-ferrule for fiber connection. Special chromated surface and burn in procedures insures low outgasing coefficients in the sealed area compared to standard black anodizing. The precise outer diameter of 20mm-h7 together with the key lock function insures excellent repeatability for multiple connection sequences. Pay attention that the gab at the collar matches the nose of the flange adaptor.(slip the screwring back to identify the gab position) The collimator has a removeable tube to cover the SMA fiberconnector for protection. To connect your fiber unscrew the tube from the collimator, and slip it together with the screw ring over the fibercable. Don`t loose the reusable dust caps for your future comfort. The collimator comes precalibrated with an LD-laser, however you should check their focal adjustment in your application. Focus adjustment can be made by loosen the lock nut on the SMA ferrule and rotating the housing counter- or clockwise. The protection tube is labeld to identify the model: AF=16 USE FOR INPUT(small lense) / AF=25 USE FOR OUTPUT(larger lense). The digits gives the achromatic focal length in mm, you may use AF=16 collimator for output resulting in smaller beam diameter but higher divergency.
4.) THE MICROPOSITIONER HMP-2: The compact and flexible design features transparent individual adjustments for coupling optimization. Both the X/Y-position and the X/Y-angle of the fiber can be adjusted separatelly to feed perfectly centered and straight the laserbeam into the fibercore. The X/Y-position adjustment is spring loaded via the adjustment screw at the bottom edge of the head, adjust this screw that you have a significant load towards the X/Y positioning spindels. The position can be finally locked in all directions by softly tightening the spring load screw and moving the metal nuts from the handnobs to the wobble plate sides. You may adjust the spring tension which holds both the reference plate and the wobble plate together via the 2 screws at the beam entry side of the reference plate. Ultraprecise angle adjustment spindels of 1/4"-80 enables even monomode fiber coupling. The micropositioner comes with a flexible assesory the L-mount-Dino for variable horizontal and vertical mounting.
5.) THE FIBER: CLP is offering a wide selection of fiber types optimized for particular applications. On request CLP is manufacturing custom specified products for your particular application - please contact factory for detailed informations and quotes. The standard fiber is an optimized 50Mikron Gradientindexfiber with TP25 Kevlar enforced tubing for broadband high power visible operation up to 12 Watts/CW. (Max. input power TEM00: 8W/CW-30micron 12W/CW-50micron 20W/CW-100micron)
Typical efficiency is 80% for 30meter/50Mikron Gradientindex cable at whitelight operation with 3 Watts TEM00/LD.
typ. 90% with TEM 00 input mode (30meters/50Mikron Stepindex)
typ. 70% with TEM 00 input mode (30meters/25Mikron Stepindex)
The fiber is finished with high quality SMA905 compatible connectors on both sides. The SMA905 compatibility gives worldwide acceptance and interchangability. The different versions of SMA finishes: -standard Connector options with epoxy free ceramic SMA and free standing fiber SMA are available for rugged high power input coupling. Each fiber is labled with length in "meters" and in case of connector option "INPUT" side. Do not loose dustcaps for future comfort.
Beam diameter Input: recommended to be max. 2.5mm / best use LD-laser div.<1.6 mrad
Beam diameter Output: typ. 3.5mm depends on output coupler and fiber type
Output divergence : less 1mrad depends on ouptut coupler and fiber type
CLP is offering repair service on all of their delivered fibers.
6.) THE FLANGE ADAPTER: This precise machined connection adapter is intended to interface the output collimator to your projector. Mounting is done via 3 screws on a circle of 30mm dia. every 120° centered to the beam path. You may use spring plate washers for the flexibility to adjust direction angles.
7.) SEE, WHAT YOU HAVE GOT: A standard fiberoptic system consists of: 1 Micropositioner - 1 Input coupler (AF=16 label) - 1 Output coupler (AF=25 label) - 1 fiberoptic cable (see length label and Input label for connector option) - 1 output flange adapter. Check that you have received everything in correct numbers and conditions. If you have ordered additional material (spare collimators, fiber cables of various length), identify them to be correct as ordered. If you recognize any mismatch in what you have received please contact factory as soon as possible - Do not ship material back without prior verification with us
The material has been checked carefully before shipping to meet all specifications, if you oberserve damage to the material when received, contact immediatelly your transportation agent for further insurance procedures. Shipping is made under the risk of the recipient with insurance value to partially cover material replacement if not otherwise stated.
8.) INITIAL SETUP AND CALIBRATION: To learn more about your LIGHTWORLD fiberoptic system, and get the most performance out of it for your application please proceed following steps as described in detail !
Turn your laser source down to the lowest possible minimum in output power level for safety reasons.
-Prepare your Micropositioner as following: adjust X/Y Position of the flange to be middle centered to the housing and adjust spring load screw to have significant tension towards the position adjustment spindels. Adjust X/Y Angle with the 2 microspindels that the wobble plate is parallel to the reference plate.
-Mount the Micropositioner in front of your laser by using the Lmount-Dino. Optimize visually the position of the micropositioner head that the beam passes through the flange adaptor symetrically centered. The flexibility of the Lmount-Dino allows you to change the horizontal and vertical position of the head to match the beam position.
- Locate your beam spot at a certain distance (e.g. 1meter) and mark it. Select the AF=16 Input collimator and insert it into the micropositioner flange adapter.(Pay attention that the gab of the collimator collar matches the flange nose, thight softly the screwring) Adjust the X/Y Position spindels that the resulting spot position is centered to the former marked beam position without the collimator. Now the Inputcollimator is perferctly centered to the laserbeam. Lock the position adjustments as described in 4.)
-Connect the fiberoptic cable with the labeled input side to Input collimator and connect the output side of your cable to the output collimator (Normally AF=25 is used for output collimator, but you may use another AF=16 collimator for short distance applications)
-Play with the angle adjustment scews to get transmission and optimize it to smallest possible output beam diameter at the exit of the output collimator-this visual optimization is close to the best coupling efficiency.
-You may recalibrate the focal adjustment on your OUTPUT collimator as described in 3.)
-You may inspect or recalibrate the focal adjustment on your INPUT collimator by reversing the coupling direction.(plug the output collimator into the micropositioner and optimize its adjustments, now the original input collimator act as an output collimator, and you can recalibrate the focal adjustment same way as described in 3.) , do not operate your fiberoptic system at high power levels when reversed !)
