The intended starting wavelength because it is useful for many common fluorescent responses.
LUMENLITHOS INSTRUMENTS · CONCEPT
Lux
Thyla.
A proposed compact UV flashlight for portable mineral observation—focused on useful excitation, controlled visible spill and honest optical performance.
NAME & DIRECTION
Thyla is a brand-derived name inspired by Greek thýlakos, a pouch or small carrying bag. Form, output, power system and specifications are not final.
01 / THE PURPOSE
Portable light.
Purposeful spectrum.
Lux Thyla is the handheld counterpart to a controlled observation instrument: a convenient light for preliminary viewing, field comparison, collection checks and photography setup.
The concept begins from the same principle as every LumenLithos light—brightness alone does not define quality. The emitted spectrum, filtering, beam geometry and stability determine what the mineral actually reveals.
02 / FIRST DIRECTION
Start with
365 nanometres.
Less visible violet
Filtering and source selection should prioritise fluorescence contrast over a visibly dramatic beam.
Useful geometry
Coverage, intensity distribution and working distance must be evaluated with real specimens.
Managed heat
Thermal design should limit output drift and protect the source during practical use.
03 / USE CASES
Made to travel
between discoveries.
A portable source can make fluorescence easier to explore, but it remains an ultraviolet instrument. Suitable eye protection, controlled exposure and attention to reflections remain necessary.
- Collection screeningQuickly compare specimens before moving to a controlled photography or observation setup.
- Field and fair inspectionPortable fluorescence checks where lighting conditions and permission allow.
- Photography preparationEvaluate composition and response before configuring fixed lights and camera geometry.
- Educational demonstrationShow longwave fluorescence with responsible handling and appropriate protection.
04 / DEVELOPMENT QUESTIONS
Specifications should follow
evidence.
Final dimensions, mass, grip and materials have not been selected.
Battery type, charging method, runtime and replaceability remain open.
Source, lens, filter and spectral leakage must be measured before claims are made.
No radiant-power or working-distance specification is currently published.
310 and 275 nm directions may be explored only if technically and safely practical.
No price, availability, production design or release date has been announced.

LIGHT THAT EARNS ITS NAME
Compact in form.
Serious about spectrum.
Development updates will be shared when measurements, prototypes and safety considerations support them.
