Other mounted lenses, prisms, mirrors and other optical elements for instruments and apparatus not named in the earlier lines, including beam splitters and light guides.

Describe the element, mount and coating on the invoice, and pack each piece in foam-lined cases. Optical and photographic goods are fragile and precision-made: pack in individual sleeves with foam, state specifications (focal length, aperture, magnification, resolution), provide CE/FCC/BIS marks for electronic cameras, keep lithium batteries under dangerous goods rules, and expect customs value checks on branded cameras.
