Nikira Labs - Model OEA -Optical Extinction Analyzers

• Measure optical extinction and visibility directly from first-principles
• Self-calibration and drift correction enables long-term field deployment
• Open Path sampling provides more accurate results
• No consumables which results in lower operating costs
• Very low maintenance costs and down time
• No external pump means lower required power and lower operational costs
• Can measure multiple wavelengths

Direct Measurement of Optical Extinction & Visibility

The Nikira Labs OEAs provide a direct measurement of optical extinction and visibility using a new, accurate and cost effective method. 

Technology

We use an open-path cavity ringdown spectroscopy (CRDS) technology. The result is a compact analyzer that can be used even aboard Unmanned Aerial Systems.

Open-Path, Self-Calibrating Measurements

Since large aerosols are difficult to sample, extinction and visibility measurement are often incorrect in smoke, fog, and haze.  The Nikira Labs solution uses a true open-path geometry to accurately measure all aerosols without extractive sampling. Moreover, periodic, automatic self-calibration assures accurate results.

Multiple Wavelengths

• 450nm, 532 nm, 632 nm, 780 nm, 850 nm, 1065 nm and 1650 nm.
• Custom: Nikira Labs offers OEAs that can operate at other wavelengths upon customer request

This turnkey, low-power analyzer can be deployed in a wide variety of environments, allowing for aerosol optical characterization in virtually any location. Use a battery (not included with the OEA) in the field or a wall plug if available.

The OEAs are designed for continuous use and while it is running, it constantly logs data to a data file. It creates a new file every 24 hours and data is backed periodically to a Google drive. The OEA has onboard data storage for more than two years of continuous data. The data can be accessed via USB or cell modem.
