Fiberscope 6650-01-502-8623 This is an optical instrument used to view objects that could not be seen by direct viewing. It contains an objective lens assembly and a bundle of systematically arranged optical fibers. The system may contain other components. The fibers transmit a full color image which remains undisturbed when the bundle is bent. See also BORESCOPE. Excludes items used for medical purposes. RFQ
Borescope 6650-01-502-8629 A viewing device used to visually inspect items such as cannon bores, internal combustion engine cylinder walls, propellant perforations of rocket motors or similar items, for defects of manufacture, corrosion, scars, erosion, etc., without the necessity of disassembling the item(s). It may or may not have extension tubes to cover the various ranges of inspection. The item is basically a straight-tube telescope using a mirror or prism. RFQ
Fiberscope 6650-01-503-2638 This is an optical instrument used to view objects that could not be seen by direct viewing. It contains an objective lens assembly and a bundle of systematically arranged optical fibers. The system may contain other components. The fibers transmit a full color image which remains undisturbed when the bundle is bent. See also BORESCOPE. Excludes items used for medical purposes. RFQ

Lens,supplementary 6650-01-503-4469 An auxiliary lens which is used in combination with a regular lens to increase or decrease focal length. RFQ
Angle Attachment;borescope 6650-01-503-5417 An item designed to change the viewing direction of a BORESCOPE (21654) in the case of inspection points which are difficult to reach. It is angular and may be rigid or adjustable. Documentation systems such as photo or video cameras may be attached at the eyepiece head. RFQ
Spacer,optical Element 6650-01-503-7561 A tubular shaped item designed to maintain a predetermined distance between optical elements, such as lenses, reticles, and the like. The bore may be straight, tapered or counterbored, and may have annular serrations to converge or diverge light rays. The surfaces, which mate with the optics, are usually chamfered, concave, and/or have a specified finish designation in the range of 1 to 125 microinches arithmetical average (AA). See also SPACER, SLEEVE and CELL, OPTICAL ELEMENT. RFQ
Casing,rigid,borescope Guide 6650-01-503-8086 A round, hollow, rigid item used to serve as a guide for the insertion of a BORESCOPE. It can be positioned (shaped) at different angles to facilitate inspections with the borescope. RFQ
