A projector or image projector is an optical device that projects an image (or moving images) onto a surface, commonly a projection screen. Most projectors create an image by shining a light through a small transparent lens, but some newer types of projectors can project the image directly, by using lasers.
At first both firms produced very similar lines of products, and extensively cooperated in product-sharing, but they drifted apart as time progressed. Jena's new direction was to concentrate on developing lenses for the 35 mm single-lens reflex camera, and many achievements were made, especially in ultra-wide angle designs.
A three-CCD (3CCD) camera is a camera whose imaging system uses three separate charge-coupled devices (CCDs), each one receiving filtered red, green, or blue color ranges. Light coming in from the lens is split by a beam-splitter prism into three beams, which are then filtered to produce colored light in three color ranges or "bands".
"The MALC™ 2.0 Triple Laser Optics embodies our relentless drive to overcome the industry’s toughest challenges," said Forrest Li, CEO of JMGO. "As the ace of laser projection, we’re always at the forefront of R&D breakthroughs, setting new standards by delivering premium viewing experiences with uncompromised picture quality."
A 100-inch projector screen can cost you anywhere from $20 on up to $200 depending on what kind you get; here's a top-rated motorized screen for $130, just as an example.
Industrial laser projectors have been on the market since the early 2000s. Laser projectors are mainly used as optical guidance systems. They enable working without templates in many manufacturing processes by showing directly on the workpiece how material needs to be positioned or mounted, so that the employee is led by manual or semiautomatic productional processes visually.
the Series XV triple-convertible lens for 10×8 inch cameras, favoured by Ansel Adams and others (also see below) the Opic and Speed Panchro large-aperture lenses, widely used by Hollywood the inverse telephoto (retrofocus) lens, created for use with the early Technicolor process, and now the standard design for wide-angle lenses in 35 mm and ...
A telecentric lens is a special optical lens (often an objective lens or a camera lens) that has its entrance or exit pupil, or both, at infinity. The size of images produced by a telecentric lens is insensitive to either the distance between an object being imaged and the lens, or the distance between the image plane and the lens, or both, and ...
