Renting time in a lab to perform a double-slit experiment may depend on various factors such as your location, academic or professional affiliations, and the availability of suitable facilities. Generally, research institutions, universities, or laboratories with physics or optics departments are more likely to have the necessary equipment and resources for conducting such experiments.
If you are affiliated with an educational institution or have connections with researchers in the field, it would be beneficial to inquire about access to their laboratories. Reach out to professors, researchers, or department administrators who specialize in optics or quantum physics to discuss the possibility of using their facilities.
Alternatively, you can also explore public outreach programs or science centers that offer hands-on experiments and demonstrations to the public. These establishments sometimes provide opportunities for visitors to engage in experiments, including variations of the double-slit experiment.
Keep in mind that availability and access to specific laboratories can vary significantly, and it's advisable to contact relevant institutions or individuals in your vicinity to inquire about the possibility of renting time to perform the double-slit experiment.
