Alstar Alignment 1.25' Next Generation Laser Collimator for Newtonian Telescopes

...he laser unit has a front opening from which the laser beam can be emitted. In order to obtain an optimal adjustment, it has a side window allowing a disk oriented at 45° with a central hole to be viewed.This can be then later be used to see whether the laser is reflected back on itself, indicating well collimated optics..
Built with metal material. CR2032 Lithium Cell battery (Not include).
Accurate collimation in a few minutes provide a more clearer image. The telescope can be collimated by just one person..
Designed for Reflector telescope, with removable 2" adapter both fit for standard 1.25 inch diameter and 2 inch diameter. Red laser collimation beam with 7 brightness levels, wavelength 635-655 nm.
Output power: less than 5mw, much safer for your eyes. This sturdy laser unit allows you to swiftly and precisely collimate your Newtonian telescope. Only when the optics have been accurately collimated can the telescope offer you its full performance..

✅【REPLACEMENT ICE MAKER OPTIC BOARD】 – The ice maker is controlled by this ‘Optics Board Kit’ that scans the level of ice in the ice container. When the ice level in the container blocks the led beam (Full of Ice) it (shuts off the ice maker). When the ice level in the container is below the led beam (Low Ice) it (turns on the ice maker). If the ice level control board fails, the ice maker will stop making ice..
