Telescope


Features
The camera to be mounted on the PRIME telescope will have four near-infrared image sensors with 4k x 4k pixels. The combination of this camera and the telescope will allow us to observe a field of view equivalent to that of six full moons at once, enabling us to efficiently search for exoplanets. Compared to other telescopes, the PRIME telescope is unique in that it has one of the world's largest fields of view in the near-infrared wavelength range.
