| lens, compound | <microscopy> A lens composed of two or more separate pieces of glass or other optical maternal. These component pieces or elements may or may not be cemented together. A common form of compound lens is a two-element objective, one element being a converging lens of crown glass and the other a diverging lens of flint glass. The combination of suitable glasses or other optical materials (plastics, minerals) properly ground and polished reduces aberrations normally present in a single lens. (05 Aug 1998) |
|---|---|
| lens, crystalline | The transparent biconvex body of the eye situated between the posterior chamber and the vitreous body, constituting part of the refracting mechanism of the eye. (12 Dec 1998) |
| lens, eye | <microscopy> The lens in an eyepiece nearest to the eye. (05 Aug 1998) |
| lens, magnetic | <microscopy> Circular electromagnets capable of projecting a precise circular magnetic field in a specified region. The field acts like an optical lens, having the same attributes (focal length angle of divergence etc.) and errors (spherical aberration, chromatic aberration, astigmatism etc.). They are used to focus and steer electrons in an Electron Microscope. (05 Aug 1998) |
| lens, negative | <microscopy> A lens that is thicker on the edges than in the centre, and which causes parallel light rays to diverge. Synonym: diverging lens. (05 Aug 1998) |
| lens, simple | <microscopy> A glass disk ground and polished with a spherical figure on one side and a plano, concave, or convex configuration on the other side. (05 Aug 1998) |
| lens-induced uveitis | Intraocular inflammation occurring after extracapsular cataract extraction;probably an immune reaction to the patient's liberated lenticular proteins. Synonym: lens-induced uveitis. (05 Mar 2000) |
| lensectomy | Removal of the lens of the eye by an infusion-aspiration cutter; often done by puncture incision through the pars plana in the course of vitrectomy. Origin: Lens + G. Ektome, excision (05 Mar 2000) |
| lenses | Pieces of glass or other transparent materials used for magnification or increased visual acuity. (12 Dec 1998) |
| lenses, intraocular | Artificial implanted lenses. (12 Dec 1998) |
| lensometer | An instrument to measure the power and cylindrical axis of a spectacle lens. Synonym: focimeter, vertometer. Origin: Lens + G. Metron, measure (05 Mar 2000) |
| lensopathy | The process by which tear proteins are deposited on a contact lens. Origin: Lens + G. Pathos, suffering (05 Mar 2000) |
| Geneva lens measure | A device for measuring the radii of the curvature of a spectacle lens. Synonym: lens clock. Origin: Geneva, Switzerland (05 Mar 2000) |
|---|---|
| vergence of lens | The reciprocal of the principal focal distance used as a measure of the divergence or convergence of parallel rays. (05 Mar 2000) |
| cataract lens | Any lens prescribed for aphakia. (05 Mar 2000) |
| meniscus lens | A lens having a spherical concave curve on one side and a spherical convex curve on the other. Synonym: meniscus. (05 Mar 2000) |
| periscopic lens | A lens with 1.25 D base curve. (05 Mar 2000) |
| photochromic lens | A light-sensitive spectacle lens that reduces light transmission in sunlight and increases transmission in reduced light. (05 Mar 2000) |
| minus lens | A diverging minus power lens. Synonym: minus lens. (05 Mar 2000) |
| collimating lens | <physics> A lens used to produce a collimated beam from a light source. With a true point source on the axis the beam would be an axial tube of parallel rays With practical sources having real area the beam will be a diverging cone of parallel rays from each light point, this beam still has special properties and can be collected again by a good lens. (05 Aug 1998) |
| plan apochromatic objective lens | <physics> A modern, high-numerical aperture microscope objective lens designed with high degrees of corrections for various aberrations. It is corrected for spherical aberration in four wavelengths (dark blue, blue, green, and red), for chromatic aberration in more than these four wavelengths, and for flatness of field. A single Plan Apo objective may contain as many as 11 lens elements. (05 Aug 1998) |
| compound lens | An optical system of two or more lenses. (05 Mar 2000) |
| concave lens | A diverging minus power lens. Synonym: minus lens. (05 Mar 2000) |
| concavoconcave lens | A lens that is concave on two opposing surfaces. Synonym: concavoconcave lens, double concave lens. (05 Mar 2000) |
| concavoconvex lens | A converging meniscus lens that is concave on one surface and convex on the opposite surface. (05 Mar 2000) |
| condenser or condenser lens | <physics> A term applied to lenses or mirrors designed to collect, control, and concentrate radiation in an illumination system. (05 Aug 1998) |
| multifocal lens | A lens with segments providing two or more powers; commonly, a trifocal lens. (05 Mar 2000) |

| lens-induced u. |
three disorders—phacoantigenic uveitis, phacotoxic uveitis, and phacolytic glaucoma—of greater or lesser severity caused by autoimmune response to lens protein leaking through the capsule. The leakage may be from hypermature cataract, capsular rupture, extracapsular lens extraction, or other trauma.
