| 摘要 |
The invention relates to a mould 10 for optical components comprising a first mould element 12 having a flat, planar surface 16, and a second mould element 14 having first and second flat, planar surfaces 18 and 20 which intersect at an angle of substantially 270{. The mould elements are shaped such that one of the surfaces of the second mould element may be placed in contact with the surface of the first mould element to provide two flat, planar, substantially perpendicular surfaces forming a hollow right-angled corner. The invention enables moulding of a component with a solid corner which is right angled to a high tolerance. The invention reduces the cost of manufacturing optical components compared to cutting and polishing techniques. If made of an appropriate material, the mould itself may be used as an optical component, e.g. a hollow right-angled corner reflector. Later embodiments relate to a method of making a mould and a method of making an optical or glass component. |
