Abstract

PURPOSE: To easily change the vertex of the angle formed of two parallel plane plates by small driving power so that optical characteristics can be changed by constituting a connecting member so as to have at least one V shape in sectional shape.
CONSTITUTION: The optical element A is the optically transparent parallel plane plate 1 consists of glass, plastic materials, etc., and is formed of the two parallel plane plates 1 when there is no energizing force from the outside. The connecting member 2 consists of the flexible materials which are formed by laminating the high-polymer films or aluminum foil, etc., and are deformable to a V shape. Water, alcohol or the like which is an optically transparent material 3 is sealed therein. Supporting members 5 support the parallel plane plates 1 in the shape of enclosing the plates and consist of aluminum, plastic molding, etc., having high hardness. The angle formed of the two parallel plane plates is easily changed by the small driving force in this way and the deterioration in the properties of the material sealed in the inside arising from a change in external environment is prevented.
