At the North East Astronomy Forum 2010, they revealed the Ethos SX, a 3.7mm focal length eyepiece with an even greater 110° apparent field-of-view. [3] In 2011, a new line of eyepieces was introduced called the Delos. These eyepieces are based on the Ethos but have a smaller field of view of 72°. Instead, they boast a comfortable 20mm eye relief.

Galilean type Soviet-made miniature 2.5 × 17.5 monocular Diagram of a monocular using a Schmidt-Pechan prism: 1 – Objective lens 2 – Schmidt-Pechan prism 3 – Eyepiece. A monocular is a compact refracting telescope used to magnify images of distant objects, typically using an optical prism to ensure an erect image, instead of using relay lenses like most telescopic sights.
A - Objective B - Galilean telescopes (rotating objectives) C - Zoom control D - Internal objective E - Prism F - Relay lens G - Reticle H - Eyepiece The stereo , stereoscopic or dissecting microscope is an optical microscope variant designed for low magnification observation of a sample, typically using light reflected from the surface of an ...
One of the most important properties of microscope objectives is their magnification.The magnification typically ranges from 4× to 100×. It is combined with the magnification of the eyepiece to determine the overall magnification of the microscope; a 4× objective with a 10× eyepiece produces an image that is 40 times the size of the object.
The telescope is more a discovery of optical craftsmen than an invention of a scientist. [1] [2] The lens and the properties of refracting and reflecting light had been known since antiquity, and theory on how they worked was developed by ancient Greek philosophers, preserved and expanded on in the medieval Islamic world, and had reached a significantly advanced state by the time of the ...
[5] [1]: 9 According to Plutarch, [6] however, the citizens of Delos consulted the oracle at Delphi to find a solution for their internal political problems at the time, which had intensified relationships among the citizens.
