Abstract
An optical instrument, for example a field-glass, in which the image-erecting system, the eyepiece tube and the objective tube are embedded in synthetic resin to form the housing of the instrument. The image-erecting system and the eyepiece and objective tubes and, if required, the hinge mechanism, are wholly or partially surrounded in cast resin to make a rigid core and this rigid core is partially or wholly enclosed in foamed synthetic resin.
