    Thorlabs ring actuated iris
    (A) Schematic of the conventional, high spatial resolution, and higher spatial resolution IR‐MALDESI optical configurations in which the beam expander and collimator are removed and replaced with <t>a</t> <t>ring‐actuated</t> iris <t>(SM1D12C)</t> positioned before a Schwarzschild‐like reflective objective (LMM15X‐P01). The adjustable iris enables fine control of beam diameter in millimeter increments, allowing systematic tuning of the laser spot size. (B) Larger iris openings (e.g., 5 mm) produce larger ablation spot sizes, resulting in lower spatial resolution. Conversely, smaller iris openings (e.g., 3 mm) yield a more tightly focused beam, enabling smaller spot sizes and higher spatial resolution.

    Figure Lengend Snippet: (A) Schematic of the conventional, high spatial resolution, and higher spatial resolution IR‐MALDESI optical configurations in which the beam expander and collimator are removed and replaced with a ring‐actuated iris (SM1D12C) positioned before a Schwarzschild‐like reflective objective (LMM15X‐P01).

Conversely, smaller iris openings (e.g., 3 mm) yield a more tightly focused beam, enabling smaller spot sizes and higher spatial resolution.

    Article Snippet: In the present work, we aim to further enhance spatial resolution by simplifying the optical setup, specifically, by removing the beam expander and collimator and instead incorporating a graduated ring‐actuated iris (ThorLabs, Newton, NJ, SM1D12C) positioned directly before a Schwarzschild reflective objective (ThorLabs, Newton, NJ, LMM15X‐P01).
