LI-180

Spectrometerr

Plant growth and reproduction are driven by photosynthetically-active radiation (PAR), which occurs at wavelengths between 400 and 700 nanometers. This interval covers three distinct “color” bands of light, and modifying the intensity of these red, blue, green wavelengths, and additional near-UV (380-400 nm) and far-red (700-780 nm) bands can provide control over a variety of plant characteristics.

The precision linear image sensor of the LI-180 captures intensity and composition of these five wavebands at the single-nanometer level with a single click. Optimize the composition of your supplemental lighting and track your spectrometer data over time for long-term validation of your lights and lighting strategy. Monitor degradation of your custom lighting system and plan for seasonal changes or upgrades.

Why Measure Spectra?

Gain enhanced control of desired plant characteristics by accurately measuring and optimizing the composition of your supplemental light.

Improve the Quality of Your Yield

Strategically modifying the spectral composition of your lights can improve the taste, nutrient content, and chemical composition of your fruits, vegetables, leafy greens, and herbs. Spectral changes can also affect stalk, leaf, and flower growth and distribution for ornamental plants.

Enhance Disease Resistance

Increasing specific wavelengths of light can inhibit the growth of and minimize the damage from mildew and other diseases common to greenhouse plants.

Why Choose the LI-180 Spectrometer?

The LI-180 provides precise, portable spectral measurement technology with flexible software options ideal for a greenhouse grower always on the move.


One-Click Data Capture

Get actionable insights in seconds. Collect multiple captures to measure changes from spectral manipulation, height adjustments, and plant positioning changes in real-time. With a single click, the LI-180 captures dozens of parameters including PAR (as color-specific photosynthetic photon flux density (PPFD)), photon flux density (PFD), irradiance (W/m2), and more.


Superior Portability

Measure your light sources from a variety of angles in and around your plants to optimize spacing and distance of supplemental light. The full functionality of the LI-180 is contained within the compact, lightweight instrument that fits in the palm of your hand. Save your data to a high-capacity SD card or transmit data files via email from the mobile application.



Instantaneous Results

Quickly deploy your light recipes and adapt your dynamic lighting strategy for species-specific responses across your greenhouse with instantaneous spectral feedback. View a variety of tabular and graphical outputs immediately after capture and create custom views to see your variables of interest.
