What is the difference between high and low resolution targets?

High resolution fluorescence test targets cover USAF groups 0–8 or 2-8, while low resolution fluorescence test targets are limited to lower groups -2-5 or 0-5. High resolution is recommended for systems needing fine detail validation.

Are the same fluorescent dye options available for low resolution fluorescence test targets?

Yes, you can choose from the same broad range of fluorescent dyes that match common fluorophores.

Are these targets reusable?

Yes, they are built to be durable and reusable under standard imaging conditions.

Can I request customized test targets?

If you have some specific needs of customized test targets for your application, contact us and we will try to meet your requirements.

The Low Resolution Fluorescence test targets deliver all the essential features of high-end fluorescent targets at a more accessible price point. Whether you’re calibrating lower-resolution systems, working on budget-conscious projects, or outfitting an educational lab, these targets provide excellent value without compromising on core functionality.

SKU: N/A Category: Fluorescence test targets

For imaging systems where ultra-fine resolution is not essential, our Low Resolution Fluorescence test targets provide a budget-friendly yet high-quality alternative. Featuring USAF resolution patterns from Group -2 to 5 or 0 to 5, and the same fluorescent backing materials available in our high-end models, these test targets are perfect for routine calibration, validation, and performance testing in fluorescence imaging applications.

Key features & benefits

USAF Resolution Groups -2 to 5 / 0 to 5: sufficient for most standard imaging system evaluations.
Cost-effective design: optimized for labs with budget constraints or moderate resolution needs.
Fluorescent background material: choose from a wide range of dye spectra that emulate common fluorophores (see below for detailed list).
Positive or negative contrast options: flexibility to suit different system requirements.
Compact, durable phantom: Robust construction suitable for repeated use.

Why Choose Low Resolution Fluorescence test targets

Not every system needs to push the limits of high-end resolution. If your application lies within the performance range of USAF Groups -2 to 5 or 0 to 5, these low resolution test targets offer the same high-quality materials and fluorescence accuracy as our premium models — at a fraction of the cost. They’re ideal for everyday calibration, teaching environments, or systems with lower optical resolving power.

Applications

Routine imaging system calibration
Entry-level or mid-tier fluorescence microscopes
Endoscopic and portable imaging devices
Medical device validation
Training and educational labs
Cost-sensitive research projects
