Precision optical table 204584

• Specially designed to address the concept of astronomical telescope • Facilitated optical alignment (all components are directly at the same height) • Possibility to also address the laws of conjugation, Galileo's telescope, and the microscope The astronomical telescope, or 'Keplerian telescope', allows for an increase in the apparent size and brightness of celestial objects during their observation. It is made up of a combination of two converging lenses, with the objective lens having a long focal length compared to the eyepiece. As it is an afocal system, the image focus of the objective lens is coincident with the image focus of the eyepiece. - 1 profiled bench 2 m with graduated feet (ref. 202958) - 6 column spacers H60 mm (ref. 204663) - 1 column spacer H40 mm (ref. 204060) - 1 warm white LED lantern with low profile with condenser, frosted "d" and power supply (ref. 204749) - 1 Clix lantern holder ring for LED lantern (ref. 204747) - 1 ring with frosted glass for LED lantern (ref. 202930) - 1 dimmer switch (ref. 203318) - 1 stopper for rod (ref. 204990) - 1 white checkered metal screen (ref. 204094) - 5 low-profile Clix supports (ref. 204253) - 7 magnetic Clix rings (ref. 204001) - 5 precision lenses Ø40 mm (focal lengths +100 (x2), +125, +300 and +500 mm) - 1 metal object token "F" (ref. 212080) - 1 millimeter token (ref. 204740) Delivered with label board.
