Plano Convex Cylindrical Lens A plano-convex cylindrical lens has curvature in the vertical direction like a convex lens, but no curvature in the horizontal direction. It is used to magnify a light beam in a single direction, for example, transforming a laser beam into a line or sheet of light, or changing the height of an image without altering its width. https://lnkd.in/g4DEFqHg

Discover our groundbreaking UV light system that will change the world of lashes forever! With our innovative technology of the light module attached to the tweezers, you can now perform eyelash extensions in record time. Our system is characterized by the following features: The light module is attached to the tweezers with the feet using magnets, which ensures easy handling. Using the spacers you can individually adjust the height of the UV light and remove it if necessary to get more magnetic surface. The light source between the tweezer tips ensures precise positioning of the light beam. By simply sliding the micro-UV attachment, the light is positioned precisely. The rotating head can be swiveled and set up directly between the tweezer tips. The light beam is directed directly at the eyelash that is being glued.

The geometry of a simple spur gear tooth is complex. Numerous dimensional parameters define the shape of the tooth profile, determine how the gears fit together, and identify locations where forces act at the gear teeth. Two of the most important parameters, often confused with each other, are the pitch diameter (d) or thread pitch diameter, and the module (m) or modulus.
