- Optics - n. - That branch of physical science which treats of the nature and properties of light, the laws of its modification by opaque and transparent bodies, and the phenomena of vision.
- Dioptrics - n. - The science of the refraction of light; that part of geometrical optics which treats of the laws of the refraction of light in passing from one medium into another, or through different mediums, as air, water, or glass, and esp. through different lenses; -- distinguished from catoptrics, which refers to reflected light.
- Chromatics - n. - The science of colors; that part of optics which treats of the properties of colors.
- Optically - adv. - By optics or sight; with reference to optics.
- Catoptrics - n. - That part of optics which explains the properties and phenomena of reflected light, and particularly that which is reflected from mirrors or polished bodies; -- formerly called anacamptics.
- Anaclastics - n. - That part of optics which treats of the refraction of light; -- commonly called dioptrics.
- Photics - n. - The science of light; -- a general term sometimes employed when optics is restricted to light as a producing vision.
