90.02 - Lenses, risms, mirrors and other optical elements, of an material, mounted, being parts o or fittin s for instruments or apparatus, other tian such elements of glass f not optically wor ed. - Objective lenses : - - For cameras, projectors or photographic enlargers or reducers 9002.19 - - Other 9002.20 - Filters 9002.90 - Other 9002.1 1 a q:i With the exception of o hthalmic lenses (which when mounted constitute spectacles, lor or the like of heading 9 .04), this headin covers the articles referred to in Items @), @) of the Explanatory Note to heading 9 .O1 when in a permanent mountin (viz., fitte in a support or fiame, etc.) suitable for fitting to anmapparatusor instrument. T%e articles of the headin are mainly designed to be incorporated with other parts to form a specific instrument or part o an instrument. The heading does not include mounted o tical elements which are in themselves separate ap liances, for example, hand rnagni@ing g asses (heading 90.13), and mirrors for medical or ental purposes (heading 90.18). f Subject to the above conditions, the heading includes : (1) Objective lenses, additional lenses, colour filters, viewfinders, etc., for photographic or cinematographic cameras or for projectors. (2) Polarising filters for microscopes or polarimeters. (3) Eyepieces and objectives (including polarising) for astronomical instruments, binoculars or refracting telescopes, microscopes, etc. (4) Mounted prisms for instruments or apparatus for physical or chemical analysis (polarimeters, etc.). (5) Mounted mirrors for telescopes, projectors, microscopes, medical or surgical instruments, etc. (6) Optical elements (lenses and prisms) for lighthouses or beacons, mounted on panels or drums. (7) Mounted lenses clearly identifiable as fittings for optical benches. (8) Mounted halftone or similar printing screens. The objective lens in an optical instrument is the lens system that faces the object, giving an image of the latter. It may be a single lens but is usually a group of lenses in a single mounting. z E epieces are optical systems (placed near the eyes) through which a magnified image is o served. The heading does not cover : elements with a temporary mounting provided solely for protection during transport (heading 90.01). (a) Optical (b) Mounted glass mirrors, optically worked, which are unsuiFble for fitting to instruments or apparatus (far example, certain rear-vlew mirrors, chimney or dram inspection mirrors, and special mirrors for wmd-tunnel observations) (heading 90.13). (c) Sets of lenses put up in cases and designed for fitting into special fiames for sight testing (used by opticians) (heading 90.18).
