Comprises:Laminated U and I cores of low-loss magnetic material, to form a closed core of cross-section 25mm in plane of laminations, 32mm perpendicular to them, I-core length 102mm, U core external height 102mm, internal height to take bobbin length 77mm.

Pair of pole pieces, each 65x30x25 mm, length x width x height with one end shapred to part of a cone for maximum flux density. Hole drilled through total length along cone exis to take a light beam. Pole pieces will accept supportrods and shading ring of accessory set 2 and may be clamped at any separation on U-Core, or in contact as a non laminated I-core.

Cast aluminium alloy stand consisting of a heavy base on four rubber feet with two removable clamping arms. Maximum dimensions of base 190x200x115mm, widthxdepthx height. Channel, 35mm wide, 3 mm deep to take transformer core, extends across full width. Integral support for arms, to rear, is below the level of the pole-pieces. Arms pivot on steel spindle with adjustment of knobs to rear bringing hard rubber pads at front end of arms to bear on transformer core. Synethetic hamme finish exvept of clean metal in channel and 4 mm hole to take an earthing plug lead.
