Fluorescence and up-conversion
Match excitation, delivery, and detection around the light your sample returns.
Application focusExcitation spectrum
Signal-to-background
Manage stray light, filters, and detector overlap.
Stable sample power
Fiber and probe losses belong in the power budget.
Why the source matters
Fluorescence systems need matched excitation lines, fiber delivery, stable intensity, and detector-aware source selection.
The correct source is defined at the sample or process—not at the laser aperture. Wavelength and operating mode set the interaction; stability, delivery, timing, and control determine whether it stays useful in the complete system.

Application workflow
Design from the result backward.
Three decisions turn the application into a practical source specification.
Map sample and detector
Capture excitation efficiency, emission band, quantum yield, lifetime, and detector response.
Budget photons at the sample
Set intensity after coupling, probes, filters, scanning, and working-distance optics.
Choose the readout mode
Define CW or modulation, timing, spectral capture, microscopy, and background rejection.
Selection guide
Match the architecture to the experiment.
These are starting architectures. Precisometer qualifies the final wavelength, output, delivery, control, and integration package against your setup.

Single-color fluorescence
A stable CW source with clean filtering and suitable delivery is often sufficient.
Multi-color imaging
Use a controlled light engine or combiner to align several excitation channels.
Up-conversion
Higher-power 808 or 980 nm sources need careful heating and delivery assessment.
