Optics. Mirrors and lenses are the critical light-bending components of a telescope. Objective: The first lens or curved mirror that collects and focuses the incoming light. Primary lens: The objective of a refracting telescope. Primary mirror: The objective of a reflecting telescope. Corrector plate: A full aperture negative lens placed before ...
Think of the eye as a camera. A camera needs a lens and a film to produce an image. In the same way, the eyeball needs a lens (cornea, crystalline lens, vitreous) to refract, or focus the light and a film (retina) on which to focus the rays. If any one or more of these components is not functioning correctly, the result is a poor picture.

Twin-lens reflex camera. The front of a Kinaflex twin-lens reflex camera. The focus rings of the two lenses are coupled with gears around their circumference in this simple design. A twin-lens reflex camera ( TLR) is a type of camera with two objective lenses of the same focal length. One of the lenses is the photographic objective or "taking ...
A photoreceptor cell is a specialized type of neuroepithelial cell found in the retina that is capable of visual phototransduction. The great biological importance of photoreceptors is that they convert light (visible electromagnetic radiation) into signals that can stimulate biological processes. To be more specific, photoreceptor proteins in ...

Red One. The Red One was Red Digital Cinema’s first production camera. [1] Using a S35mm image plane, the Red One displays a natural depth of field from 2K to over 4K resolutions. [2] The first Red Ones were outfitted with the 12 megapixel Mysterium sensor, capable of capturing up to 120 frames per second at 2K resolution and 30 frames per ...
