  • Publication number: 20230408803
    Abstract: A spacer for an immersion objective lens can be fabricated by pressing a set of sidewalls onto a mirror to form a liquid-tight cavity, filling the liquid-tight cavity with a first quantity of a UV-curable polymer, and curing the first quantity of the UV-curable polymer into a first solid mass that will be adhered to the mirror. The upper surface of the first solid mass is then positioned near the objective lens, with a second quantity of a UV curable polymer occupying the space between the first solid mass and the objective lens. Next, the position of the first solid mass is adjusted until it reaches a final position with respect to the objective lens. This adjustment may be assisted by checking the collimation of light reflected back through the mirror. The second quantity of the UV curable polymer is then cured.
