Nu Instruments | Extending Imaging Dynamic Range Using Multiple Shots per Pixel 

This application note explains how multiple laser shots per pixel and composite imaging techniques can improve elemental image quality. It demonstrates how researchers can increase dynamic range while maintaining high-resolution imaging performance.

Images rendered for 57 Fe over the same sample area using either the ion beam attenuated or full ion beam method where the occasional detector protection event can be seen where nearby isotope signal has been overrange.

High-speed imaging often requires a balance between spatial resolution, sensitivity and dynamic range. This application note shows how multiple laser shots can be combined within a single pixel to enhance detection of low-level signals without significantly increasing acquisition times.


The note also introduces composite imaging workflows that merge attenuated and unattenuated datasets. This approach enables accurate measurement of both major and trace elements within the same image.


By combining advanced laser ablation strategies with flexible data processing, Vitesse helps users achieve broader analytical ranges and greater image clarity across complex samples.
