BACKGROUND:
Notice is hereby given by the University of Ottawa of the intent to enter into a contract with Aerotech to procure a multi-axis motion system. The proposed system is to be used with an ultrafast laser system to position the samples to be laser machined very accurately (nm resolution) over large distances (200 mm) at high speeds (5 m/s). This motion system coupled with the ultrafast laser will support the research programs of the applicant on surface texturing of materials applied to biocompatibility, battery materials, wettability, and optical effects (colours).
PROCESS;
Suppliers who consider their equipment functional, successfully tested, readily available and fully compliant to the ACAN minimum requirements may submit in writing a statement of specifications to the contact person identified in this Notice, on or before the closing date of this Notice. In the statement of specifications, the supplier must unequivocally demonstrate how their equipment, at minimum, equals or exceeds the stated requirements.
If no other supplier submits a statement of specifications, on or before the closing date of this Notice, the competitive requirements of the University of Ottawa will be considered having been met.
Following notification to suppliers not successful in unequivocally demonstrating that their statement of specifications equals or exceeds the requirements set out in this Notice, the contract may then be awarded to the pre-identified supplier.
Date of issue: November 17, 2022
Closing Date: December 2, 2022, at 3:00:00 P.M. Eastern Standard Time
INTENDED USE:
This multi-axes motion system will be integrated into an ultrafast laser set-up with which it must interface.
The multi-axes motion system consists of the following minimum requirements as follows:
- A low-profile direct drive nanopositioning X-Y-axes stage, bidirectional repeatability 100 nm, straightness 500 nm, 200 x 200 mm travel, with a max velocity of 200 mm/s, a payload of 5 kg,
- A low-profile direct drive nanopositioning Z-axis stage, bidirectional repeatability 75 nm, 110 mm travel, max velocity 150 mm/s, payload 5 kg, to hold the existing galvanometric scanner head
- A miniature Gear-Driven Rotary Stage with aperture lens mount, repeatability 8 arc sec, max speed 23 deg/s, 360 degrees continuous rotation.
- Integration of X,Y,Z stages on a granite structure consisting of a baseplate with dimensions of 1070 mm x 620 mm x 150 mm, risers with dimensions of 150 mm x 150 mm x 300 mm and bridge with dimensions of 1070 mm x 600 mm x 150 mm. XYZ stages must be calibrated for accuracy on the granite structure to ensure precise, orthogonal alignment of the stages. Parameter file generation, system tuning, and documentation of the system configuration must be provided for the whole system installed on the granite structure.
- Software to operate these stages simultaneously (especially using the infinite field of view synchronization between the galvanometric scanner and x-y stages).
- The Aerotech controller hardware must be a perfect match with the existing Aerotech galvanometric scanner currently in the researcher’s lab and must reach the specifications provided by Aerotech’s galvanometric scanner (e.g., Accuracy 50 µrad pk-pk, Repeatability 0.4 µrad RMS, scan angle ±20°, etc.)
Justification of Pre-Selected Supplier:
Supplier: Aerotech
Justification:
- Aerotech is the only supplier that can provide the multi-axes motion system for it to be to be compatible with the current systems available in the researcher’s lab, which are from Aerotech. In particular, the Galvanometric scanner will need to be installed on this new system and can only be synchronously operated with the other stages with an Aerotech controller.
- In addition to the galvanometric scanner, two rotation stages (for tilting and rotating the sample under the laser beam) currently in the researcher’s lab will need to be utilized with the new Aerotech system proposed here.
- Codes currently written in Aerotech’s proprietary code will need to be rewritten if going with another vendor, resulting in significant delays in the research.
- Aerotech is also the only company that can achieve the high positioning resolution required over large distances and at high speed.
