Optics, as a field, is often considered largely separate from the physics community. It has its own identity, societies, and conferences. The pure science aspects of the field are often called optical science or optical physics.

Optics is a very important and fundamental Nikon technology. We at Nikon are engaged in advancing optical technology that will bring new possibilities to various fields, from cameras and microscopes to IC steppers and scanners.
DxO Optics Pro Review
The most well known feature of the award winning DxO Optics Pro from DxO Labs is its ability to correct perspective distortion, but this isn't what sold me on switching to it as my preferred raw converter.

Apart from the CCD in a digicam, the lens is the most important element to ensure a quality image. Most digicams have zoom lenses which allow you to vary their focal length from wide-angle to telephoto.

The letters DO stands for diffractive optics. I won't go into the technical details of how these lenses work, as this information is already listed on a wikipedia article about Defractive Optics.
OPTICS - The branch of physical science that deals with the properties and phenomena of both visible and invisible light and with vision.
Clean Optics
It is quite easy to touch the optics of a camera and leave fingerprints. The result is that your pictures do not turn out clear in certain areas.
Fiber Optics
An optical system that uses glass or transparent plastic fibers as light transmitting media.
File Format
A type of program or data file. Some common image file formats include TIFF, PICT, and EPS.
Fiber Optics

Good optics (sharp, most shutter speeds are HIGH, better low-light performance)
Little need for post-processing (good levels, good colours, sharp)

Non-imaging optics is an approach to collecting, concentrating and transporting light. As the name suggest, a non-imaging optic does not produce an image of the light source, but rather...

There are add-on optics for these cameras that can enhance close-focus capability. Or if you are working with a macro lens on a housed camera, your range would be from within a few inches in front of the lens port to 6 feet.

Collimation This refers to how correctly the optics are pointing towards each other. If a telescope is out of collimation, you will not get as clear an image as you should.

Enlarging usually produces positive images that are larger than the negative image; however, because optics are used in projection printing, the image formed on the paper can also be made smaller or the same size as the negative image.
These optics are great for those who want to travel light but still be able to cover everything from wide-angle to telephoto shots. A few years ago, I would not have recommended this type of zooms as they were not optically as sharp as other lenses.
An image sensor of about 1 square inch requires super excellent optics if the resulting images are going to be made into big prints.
For film cameras, now that lenses have been designed that minimize the distortion of different colors of light bending differently, there isn't much of a problem if we use high-quality optics, ...

Bokeh (Japanese "boke" = blur or haze) is how the lens draws unsharp image areas.
Optical zoom means the camera is using its optics to gather an image, same as an SLR. Digital zoom means the camera is taking the image delivered by its optics and digitally enhancing the image.
If you get hooked on this stuff and feel the need to upgrade your equipment, spend your money on lenses -- better quality optics and faster auto focus. A camera with a higher frames-per-second rate will help, but not if the frames are of poor quality.
Long zoom compacts depend heavily on the quality of the optics, so no expense has been spared to provide the FinePix F80EXR with the sharpest, clearest Fujinon 10x zoom lens.
All apparently use the same optics - they just have different cosmetic styling of the lens barrel (the mark III version, for example, has a silver ring on the end to impress novice camera buyers) and different autofocus motors.
The same has happened in the photographic industry: although digital photography is firmly here to stay, there’s been a resurgence of interest in vintage lenses, generating a healthy market for high-quality optics that have been gathering dust ...
Founded as a workshop for precision mechanics and optics in the German city of Jena in 1846, Carl Zeiss is today a global leader in the optical and opto-electronic industries.
Whereas an optical zoom uses the optics (lens) of the digital camera to move you closer to your subject, a digital zoom simply uses the existing image and enlarges it digitally.
Be sure to choose a camera with a glass lens rather than a plastic one, and look for a lens that bears the name of a reputable optics maker. An optical zoom is also a useful feature for a camera phone lens.
Digital image anomalies caused by the image sensor, optics or internal image processing of the camera.
When it comes to the optics and resolution, you won't be disappointed with the Nikon D90. It produces slightly bright shots in daylight with those pleasing and natural colors. The ISO range is from 200 to 3200 for a total of 11 settings.
With predictions that camera phone sales will soon vastly outnumber sales of all other types of cameras combined, most major Japanese camera and lens manufacturers are furnishing optics OEM to the phone companies.
Really good optics minimize color fringing, but some fringing is inevitable, especially when corner areas of an image are highly magnified.
Part of the problem is that your camera's optics introduce distortion when rendering broad panoramas on tiny, two-inch screens.
Many of the innovations in optics and cameras that have led to today's digital photography technology came from the minds and workmanship of the people at Canon, Inc.
Macro - Macro lenses are lenses where the optics allow for high magnification of subjects. "True" macro lenses record the image at the same size as it appears in real life. This is a 1:1 macro. Not all macro lenses are actually "true" macros.
The optics are excellent. No vignetting, and zoom works fine. Auto-Focus works fine, and the depth of focus is extremely deep. With manual focus you can focus to just before infinity, and everything will be in focus.
It is very easy to scratch the fine optics. A lens cleaning kit is not expensive and is well worth the money.
The term 'focal point' in photography also applies to optics, where it represents a point in space where rays of light converge after they have been affected by an optical system.
But, you can't just measure the outside of the lens because manufactures can do some pretty funny stuff with the optics to modify the effective FL. Generally, a 50mm lens for a 35mm camera is equal to your eye.
Perspective Control Lens: A wide angle lens design featuring optics that can be shifted to correct for converging vertical lines, inherent in wide angle lenses.
We do not need to study optics to understand rainbows. The only thing we need to care about is the position of the sun, the water droplets and the photographer.
Understanding your subject matter - the scene, your raw materials - elements and attributes, your tools - the camera, lenses, filters, film, basic rules of optics and exposure, etc. is only a first step.

PhotoAcute Studio corrects geometric distortion caused by the camera optics. This gives photographs the right perspective and a natural look.
Almalence's super-resolution technology supports automatic algorithm tuning to particular cameras and optics. That makes it possible to achieve maximal image improvement for every imaging system.
Then, consider the trade-off between the optics quality, the camera's weight, the convenience of a prime vs. a zoom lens, lens speed, focal distance and price. Often it will be a balance of these considerations that leads you to a good camera.
Resolution - The number of pixels or dots per inch in an image. Also the capability of a scanner to resolve detail, which requires quality optics as well as high ppi or spi.
Retouch - To remove flaws or to create a new effect in an image.
