Manufacturing method of optical casting having holographic optical element

摘要

The present invention relates to a method for producing an optical casting comprising at least one volume holographic optical element by a casting process, the method comprising the following steps: a flat, spherical, non-spherical or free-form first surface Providing a casting mold (30) comprising a first mold part (10) having a second mold part (20) having a flat, spherical, non-spherical or free-form second surface. Providing a first mold part (10) connectable to the second mold part (20) to form a casting mold (30); providing at least one holographic optical element (91) Placing the at least one holographic optical element (91) relative to the first mold part (10) and / or the second mold part (20). Aligning the first mold part and the second mold part to form the casting mold (30); introducing the casting material into one or more casting processes, The casting material having a maximum viscosity of 100,000 mPas at 25 ° C .; curing the casting material; removing the cured casting material comprising at least one holographic optical element (91) from the casting mold (30) A casting material extending at least partially around at least one holographic optical element (91).
