The Prospective Instruments MPX-series is a turnkey compact multimodal microscope enabling advanced multiphoton imaging without requiring a laboratory or optical bench. One of the key design features is the ultrafast fiber laser engine integrated into the free moving scan head, which is lightweight, rugged, and allows the ultimate imaging flexibility. A modular design concept allows the user to explore a wide variety of biological applications and measurements, without compromising performance, in any indoor working space. In contrast, standard setups are non-transportable, utility-demanding, and the complexity can be complicated, therefore degrading the value and adding significant initial, short- and long-term expenses. Every clinical and biological researcher should have access to high-quality reliable optical microscopy modalities without being hardware experts. In this article we outline the demand and design of the MPX-microscope and present multiphoton imaging results from experiments in various configurations. There are no existing instruments on the market that are portable and combine easily switchable modes in one composite industry-ready device for life science, clinical, and pharmacological research.

Despite its vital role in advancing live cell imaging (LCI) and unraveling the complex processes that control cellular function, fluorescence microscopy presents challenges for the researcher, including labeling agents that can interfere with normal molecular activities, and limitations on repeat measurements and long-term studies from photobleaching and phototoxicity phenomena. Holotomography microscopy delivers nanoscale, label-free, real-time LCI and can combine this quantitative phase imaging (QPI) with fluorescence for state-of-the-art spatiotemporal resolution as well as high molecular specificity. This article introduces QPI, examines its advantages for LCI, and reviews correlative microscopy studies in cell pathophysiology in combination with fluorescence.
