Definition
Violet 3.0 is HAWK Biosystems' purpose-built microscopy platform for QF-ProLoading... technology. This compact benchtop system integrates a high-end modulated laser, sensitive two-tap CMOS image sensor, and multi-channel LED illumination into a single maintenance-free unit. Designed with simplicity as a core principle, Violet 3.0 enables any laboratory—regardless of prior FLIMLoading... experience—to perform spatially-resolved FRETLoading...-based functional proteomics on tissue samples.

System Overview

Violet 3.0 represents a paradigm shift in FLIMLoading... instrumentation: laboratory-grade functional proteomics without the complexity. Traditional FLIM systems require specialized training, complex alignment procedures, and significant maintenance. Violet 3.0 eliminates these barriers.

The system tagline—"Simplifying FLIM/FRET to empower life science research"—reflects its design philosophy. Where simplicity meets innovation, whole new avenues of research become accessible to laboratories that previously lacked FLIM expertise.

Simplified

Violet 3.0 is like having a specialized camera that can see whether proteins are actually working together—not just whether they're present.

📸 The Smart Camera Analogy
A regular microscope is like a standard camera—it shows you what's there.

Violet 3.0 is like a thermal camera that shows you what's active. It doesn't just see proteins; it sees which ones are actually doing their job.

This matters because two tumors can look identical under a regular microscope but behave completely differently. Violet 3.0 reveals the functional differences.

QF-Pro Software Integration

What makes Violet 3.0 accessible is its accompanying QF-Pro software suite. This guides users of all experience levels through:

• Sample Loading: Visual guidance for slide/plate positioning
• ROI Mapping: Create regions of interest for sequential acquisition
• Automated Analysis: Platform calculates QF-ProLoading... scores and generates images per region
• Post-Acquisition: Threshold application, LUT adjustment—automated with fine-tuning options
• Export: Seamless output to Excel (data) or PowerPoint/PDF (images)

The software provides end-to-end workflow integration—from sample to publishable results—with cross-platform compatibility for files from other FLIM devices.

Simplified

The software is designed so that anyone can use it, not just FLIM experts.

It walks you through each step:

  • Put your sample in → software shows you where
  • Mark what you want to image → click and drag
  • Press start → machine does the rest
  • Get results → ready for Excel or PowerPoint

No PhD in optics required.

Key Capabilities

Violet 3.0 delivers capabilities previously requiring research-grade confocal systems:

• Functional Proteomics: Quantifies protein-protein interactions (iFRETLoading...) and activation states (aFRETLoading...) directly in tissue
• Spatial Mapping: Maps functional proteomic events across the tumor microenvironment
• Multiplexed Readout: 4 biomarker expression profiles + 1 functional QF-Pro map in a single acquisition
• High Throughput: Automated, robust operation for multi-sample studies

This combination makes Violet 3.0 the only clinically validated spatial biology platform in the immuno-oncology domain for functional biomarker measurement.

Safety Features

Violet 3.0 is classified as a Class 3B laser product per IEC 60825-1:2014. Safety features include:

• Full Light Sealing: Enclosed optical path prevents exposure
• Mechanical Interlocks: On all openable panels
• Light Interlocks: Automatic laser shutoff when panels opened
• Key Switch: Required for initial operation

The system is designed for routine laboratory use without requiring dedicated laser safety infrastructure beyond standard precautions.
