VIS and NISP Instrumentation.
To achieve this extensive protection, VIS is equipped with 36 CCDs (Charge Coupled Devices, a kind of video camera sensing unit), set up in a 6 × 6 grid; each sensing unit having more than 4000 × 4000 pixels. The NIPS instrument is fitted with a 4 × 4 grid of near-infrared sensing units of more than 2000 × 2000 pixels each. While VIS determines the shapes of the galaxies, NISP steps their brightness (and how it changes over wavelengths), needing a smaller sized number of detector arrays that have larger pixels.
Euclid is the only telescope that currently can observe such a big location of the sky in one single sitting with such sharpness, in near-infrared and visible light.

It highlights that the location of the sky that Euclid can observe within one pointing of the telescope, is larger than that of the full Moon. Euclids gaze captures in one single observation a square area of the sky of about 0.7 times 0.7 degrees. The accompanying figure displays an overlay of an image of the Moon atop a sky image concurrently caught by the 36 detectors of Euclids VIS instrument. The Moons size covers roughly 0.5 degrees, whereas Euclid can observe a square location of the sky determining about 0.7 by 0.7 degrees in a single observation.
This figure reveals an overlay of a picture of the Moon on top of an image of the sky taped all at once by the 36 detectors of Euclids VIS instrument. The VIS image was gotten in one single shot throughout the preliminary months of testing of the spacecraft. It shows that the area of the sky that Euclid can observe within one pointing of the telescope, is bigger than that of the moon. The aperture angle of the Moons size is approximately 0.5 degrees.

Euclid, the European Space Agencys dark Universe investigator, was introduced on July 1, 2023. It has just recently showcased its very first full-color, spectacular images of the universes, boasting effective imaging capabilities thanks to its distinct optics.
Telescope and Imaging Technology.
Euclids telescope and its optics are specifically created to catch a large view of the sky in a single shot. This function is crucial for its objective, which intends to map over one-third of the celestial sphere with high sensitivity within a six-year timeframe.
Image Comparison and Coverage.
The accompanying figure shows an overlay of a picture of the Moon atop a sky image at the same time recorded by the 36 detectors of Euclids VIS instrument. This image, obtained in a single shot throughout the spacecrafts early screening stage, demonstrates Euclids ability to cover a location larger than the moon in simply one telescope pointing. The Moons size spans approximately 0.5 degrees, whereas Euclid can observe a square area of the sky measuring about 0.7 by 0.7 degrees in a single observation.
