Description

The Collimated Beam Projector (CBP) is a new device to measure instrumental throughput of a telescope. We will detail the performance of a CBP version built at LPNHE and show that we reach a permil calibration of the CBP throughput itself thanks to a calibrated solar cell, and of the StarDice telescope. We will present news from the Rubin Obs. CBP under construction.
