University of Twente (UT) wishes to be as transparent as possible towards the market. In addition, UT wishes to prevent legal uncertainty (a possible nullification of the agreement based on Article 4.15 Public Procurement Act 2012). For this reason, UT hereby publishes an 'ex ante announcement' within the meaning of Article 4.16 paragraph 1 sub b Public Procurement Act 2012, in which it expresses its intention to directly award a contract. Below, UT will further explain why it believes that the contract can be awarded directly, without prior notification as referred to in Article 4.16 paragraph 1 sub a Public Procurement Act 2012. Finally, UT will provide information about the legal protection available to entrepreneurs to object to the intention to award the contract.
Laser for the Physics of Fluids group for the proposed Laser-Induced-Fluorescence measurement planned with double dyes with the following requirements:
-Integrated laser and OPO without manual alignment (so not two devices; too large and needs alignment every time we move it).
-OPO tunable in the visible-light spectrum 410nm–710nm.
-Pulsed DPSS laser with 100Hz repetition rate.
-Pulse energy up to 20mJ.
-Pulse duration -Output energy stability: less than 0.4% RMS.
-Integrated laser, cooler, and motorized OPO wavelength with a closed loop diode feedback for stability of the wavelength and power. The feedback loop should correct for temperature changes in the DPSS and the OPO to make sure the wavelength and power does not change over time/with temperature.
-Additional 532nm beam exit.
-Software to control power, frequency, and the wavelength dynamically.
-TTL trigger input.
-Invar construction for robust operation (prevents warping of the housing due to the temperature changes causing mode hopping).
-230V connection.
-Operational in 15–35 degrees C ambient temperatures.
