Precision optical table 204125

Specially designed to address the concept of astronomical telescope. Optical alignment made easy (all components are directly at the same height). Also possible to cover the laws of conjugation, Galileo's telescope, and the microscope. The astronomical telescope, or 'Keplerian telescope', allows for increasing 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. This design includes column-mounted carriers with perforations to fix the spacing of each optical system (object at infinity, astronomical telescope, and imaginary eye). - 1 profiled bench 2 m with graduated feet (ref. 202958) - 7 column pierced riders (ref. 204124) - 1 warm white LED lantern with low profile with condenser, frosted "d" and power supply (ref. 204749) - 1 Clix lantern key 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) - 3 optical axes Ø10 mm of respective lengths 490, 245 and 175 mm Delivered with label board.
