Fluorescence Lifetime Imaging (FLIM) is increasingly used in biomedical imaging and clinical diagnostics, but many systems don’t require ultra-fine resolution for effective calibration, that’s where our Low Resolution FLIM Test Targets come in — a cost-effective, lifetime-calibrated solution built for standard-resolution imaging platforms.
Designed using USAF resolution patterns ranging from Group -2 to 5 or 0 to 5, and embedded with characterized fluorescent dyes (BPXS1LT, BPXS3LT, BPXS4LT, BPXS5LT), these targets offer traceable fluorescence lifetimes in a format optimized for lower-resolution FLIM systems. They’re ideal for system validation, software testing, training environments, and labs with budget or resolution constraints.

Why Choose Low Resolution Fluorescence Lifetime test targets
Not every FLIM system needs to push the limits of high spatial resolution—but all of them need reliable, reproducible calibration. These low resolution fluorescence lifetime test targets fill a critical gap for users who value:
-
Affordability without compromising quality
-
Valid lifetime benchmarks for quantitative imaging
-
A tool that supports routine quality control across different platforms
-
A reproducible solution backed by long-term stability studies
Until now, labs often relied on unstable liquid dye samples or custom setups. This is the first commercial solution offering reproducible solid-state FLIM calibration optimized for mid-range and portable imaging systems.
Applications
- FLIM-based clinical and preclinical system validation
- Training environments and educational FLIM labs
- Imaging platforms with limited spatial resolution
- Software benchmarking and algorithm development
- Longitudinal studies in drug screening and cell metabolism
- Low-cost instrument manufacturing and quality assurance
