The project is now in its fourth phase. The first phase, OGLE-I (1992–1995), used the 1.0-metre (3 ft 3 in) Swope telescope and a single-chip CCD sensor. For OGLE-II (1996–2000), a 1.3-metre (4 ft 3 in) telescope dedicated to the project (the Warsaw telescope) was constructed at Las Campanas Observatory. It was equipped with a single 2048× ...
As of December 2019, all SPECULOOS - South telescopes are operational. [1] ESO released first light images of SPECULOOS - South on the 2018-12-05. The telescopes did take images of the Carina Nebula, the Horsehead Nebula and the spiral galaxy Messier 83. [2] Artemis is the first telescope for SPECULOOS - North (SNO) it began operations on June ...
This list covers optical lens designs grouped by tasks or overall type. The field of optical lens designing has many variables including the function the lens or group of lenses have to perform, the limits of optical glass because of the index of refraction and dispersion properties, and design constraints including realistic lens element center and edge thicknesses, minimum and maximum air ...
Telescopes can be classified by optical design or mechanical design/construction. Telescopes can also be classified by where they are placed, such as space telescopes . One major determining factor is type of light, or particle being observed including devices referred to as "telescopes" that do not form an image or use optics.
OSLO provides an integrated software environment that helps complete contemporary optical design. More than a lens design software, OSLO provides advanced tools for designing medical instrumentation, illuminations systems and telecommunications equipment, to name just a few typical applications.
In the original spectroscope design in the early 19th century, light entered a slit and a collimating lens transformed the light into a thin beam of parallel rays. The light then passed through a prism (in hand-held spectroscopes, usually an Amici prism ) that refracted the beam into a spectrum because different wavelengths were refracted ...
SPECULOOS-3, also known as LSPM J2049+3336, is a red dwarf star (spectral type M6.5) located 54.6 light-years from Earth [4] in the constellation Cygnus.It is one of the smallest known stars, and is much cooler, dimmer and smaller than the Sun, having 0.1 times the mass, 0.08% the Sun's luminosity, and an effective temperature of 2,800 K (2,530 °C), which is less than half of the Sun's ...
From an aerial view of the Paranal Observatory, the four large units of the VLT with their four small, dome-shaped auxiliary telescopes can be clearly seen. The Survey Telescope, VST, is immediately adjacent to the VLT and seen in between two of its units, while VISTA is located on a secondary peak, some 1,500 m away in the background (see image).
