摘要:
The present invention relates to a reflective optical objective (1) comprising: —a first reflecting element (3) including a front surface (3a) and a hack surface (3b), the front surface (3a) including a convex reflecting surface (11) and —a second reflecting element (5) including a concave reflecting surface (13) facing the convex reflecting surface (11) of the first reflecting element (3), the second reflecting element (5) including a transmissive section (7) permitting electromagnetic radiation to pass through the concave reflecting surface (13) of the second reflecting element (5) to the first reflecting element (3). The reflective optical objective (1) is characterized in that the reflective optical objective (1) includes a carrier material (9) embedding at least the front surface (3a) of the first reflecting element (3) and defining the distance (d) between the first (3) and second (5) reflecting elements.
