ALPhA (Advanced Laboratory Physics Association) has worked out a deal with Excelitas to sell Single-Photon Counting Modules (SPCMs) to instructional labs. The detectors carry labels specifying that these units belong in the undergraduate instructional labs and not in research labs. These educational detectors have reduced specs, notably a higher background dark count rate, compared to other models from the company.
The set of four SPCMs can be purchased for $5,720 (instead of the usual ~$10k).
This price is only available to ALPhA members, and SPCMs can only be purchased through a group order placed by ALPhA (15 institutions each ordering a set of four detectors).
