Method and apparatus for positioning and fixating an optical element

A method for positioning an optical element and fixating said optical element onto a base plate, said method comprising the following steps of:

• a) holding said optical element in an aligning chuck;
• b) bringing said aligning chuck and said optical element into a predetermined position and orientation, whereby a first attaching surface of said optical element remains in a predetermined orientation with respect to a fourth attaching surface of said base plate;
• c) contacting a side mount with said optical element and with said base plate, whereby:
• I. said side mount has a second attaching surface and a third attaching surface;
• II. said first attaching surface and said second attaching surface essentially correspond in position and orientation;
• III. said third attaching surface and said fourth attaching surface essentially correspond in position and orientation;
• IV. a first adhesive is applied between said first attaching surface and said second attaching surface;
• V. a second adhesive is applied between said third attaching surface and said fourth attaching surface;
• d) curing said first adhesive and said second adhesive;
• and
• e) removing said aligning chuck.

• and
• g) removing said aligning chuck.

An optical device consisting of an optical element and a side mount, wherein:

• a. said optical element being essentially rectangular in view of an optical axis of said optical element;
• b. said side mount being essentially rectangular in view of said optical axis;
• c. said optical element being attached on said side mount lateral to said optical axis;
• d. an upper portion of said optical element raising above said side mount;
• e. said side mount being attached with its bottom side on an assembly plate;
• and
• f. said side mount having a chamfer between a side mount top face and a side mound side face, said side mount side face being in opposing position to said optical element.
