developer kit
Luxnode base preorder.
The first devkit is for calibrated spectra, local Python access, cloud sync, and module development. Regulated medical, environmental, or laser workflows require their own validation and certification path.

Price follows the current component-cost plus 30 percent formula, rounded to the next 100. Final production pricing can change as optics, enclosure, and compliance costs settle.
external modules
measurement heads for the first spectroscopy workflows.
uv absorption
UV quartz cuvette module
Quartz-cuvette optical path for UV absorbance workflows: oil oxidation trends, dissolved organics, reagent assays, and blank-corrected liquid scans.
developer accessoryliquid sample compartment
food and oil cuvette compartment
Low-volume liquid insert for oil grading screens, color-body tracking, sugar-content models, and fat-breakdown proxies after calibration against reference assays.
developer accessoryleaf reflectance
plant reflectance module
Clamp-style leaf fixture for chlorophyll proxies, vegetation health scores, pigment balance, red-edge trend tracking, and stress experiments.
developer accessoryrock/mineral reflectance
mineral reflectance module
Contact nose for current UV/VIS geology: iron-oxide/weathering signatures, soil organic matter, oil/PAH fluorescence, and broad library matching.
developer accessoryfuture mineral group ID
SWIR mineral reflectance module
Future SWIR head for stronger carbonate, sulfate, and clay group identification from OH, carbonate, and sulfate absorption bands.
future accessoryfuture elemental emission
LIBS high-resolution mineral module
Research preorder track for elemental LIBS. The current 8-15 nm optical heads are not suitable for elemental line ID; this module requires a high-resolution emission spectrometer plus certified laser controls, enclosure/interlocks, and qualified operation.

hand telescope spectroscopy adapter
Passive printed rail and nose adapter to couple a small handheld telescope to the Luxnode slit/fiber input for dark/flat-corrected stellar captures.
astronomy accessoryreserve / request modules
preorder the devkit, then list the modules you want.
Use the notes field for external modules and accessories. For food and oils, list the reference assay or grade standard. For plants, note crop and stress target. For minerals, list whether you want UV/VIS reflectance, future SWIR group ID, or high- resolution LIBS elemental analysis. For astronomy, note the telescope diameter, eyepiece/focuser size, and targets you want to classify first.
