Abstract
A second optical element is bonded to a first optical element by forming the second optical element by pressing a second optical element material against the first optical element under a condition free from restriction to the second optical element material in the direction orthogonal to a direction in which the second optical element material is pressed.
Claims11
A bonded optical element comprising a first optical element and a second optical element bonded to each other by forming the second optical element by heating and pressing against the first optical element a second optical element material, wherein
- the second optical element is formed by pressing the second optical element material against the first optical element under a condition free from restriction to the second optical element material in a direction orthogonal to a direction in which the second optical element material is pressed, and
- the first and second optical elements are made of glass materials.
A method for manufacturing a bonded optical element in which a first optical element and a second optical element are bonded to each other by forming the second optical element by heating and pressing against the first optical element a second optical element material, the method comprising the step of:
- forming the second optical element by pressing the second optical element material against the first optical element under a condition free from restriction to the second optical element material in a direction orthogonal to a direction in which the second optical element material is pressed.
