Pleiades telescope about 7 times and improve efficiency

It was reported recently the world's largest single-lens telescope "telescope Pleiades" were installed on the second generation of ultra-wide-angle prime focus camera "Hyper Suprime-Cam" (hereinafter abbreviated as HSC). New equipment so that the telescope to observe the sky in a region shorten the time required for about 7 times, greatly improving the efficiency of observation.

"Pleiades telescope" is located in Mauna Kea, Hawaii, the telescope has a diameter of 8.2 meters. Scientific monitoring since 1999 since its discovery in the farthest galaxy has created many new record for space observations contributed to the work. The installation of a new generation of ultra-wide-angle camera is the main focus of the company involved in R & D by Canon and production.

Pleiades telescope lens sophisticated interior design, size and quality must meet strict limits, it is understood, by virtue of Canon design technology accumulated over the years as well as the current task newly developed measurement techniques and precision machining technology, the lens maximum angle from the first generation Suprime-Cam * 3 (SC) achieved increases to 0.5 degrees 1.5 degrees.

While the new correction lens by using a non-spherical lens such that a viewing angle may be about three times as large SC perspective, but it only uses a seven lens elements, with the same number used in the SC, and the lens diameter is about previous 1.6 times as large. In weight, the unit of the lens barrel (which role is to ensure a high-precision lens can always) the new use of a ceramic material, a lens barrel in the previous used materials, which can significantly reduce the weight. This ceramic lens barrel production also features Canon's precision machining technologies.


In recent decades, with the advancements in the field of space research, the secrets of the universe gradually been found in the field of exploration of the unknown, humans have never stopped the pace.

The HSC development and use of human space exploration marks the further development of the universe makes it possible to carry out wide-field observations, so that we can uncover the origins of the universe and the mysteries of the future road getting faster and faster.
