Annual factory calibration is essential to ensure accurate ozone, aerosol optical thickness (AOT), water vapor, and solar radiation measurements. Take advantage of our annual calibration program at the Mauna Loa Observatory in Hawaii—a unique high-altitude location that provides ideal atmospheric conditions for precise instrument calibration. Submit your instrument(s) by June 26, 2026 to be included in this year’s calibration. Early submission is recommended, as all systems will need to be...

Sensor technology continues to advance rapidly across all regions of the electromagnetic spectrum, from ultraviolet through visible and into infrared, enabling increasingly sophisticated and complex applications. Addressing these demands requires a spectroradiometric system that is not only highly reliable and precise, but also robust and adaptable enough to accommodate a wide variety of measurement scenarios and evolving requirements. The OL 750-series monochromator provides a versatile...

Displays and lighting systems used in military environments—where personnel operate Night Vision Imaging Systems (NVIS)—must provide clear, legible information under near-dark conditions. To meet these demands, manufacturers are required to comply with MIL-STD-3009 (which supersedes MIL-L-85762A). Appendix A of this standard defines the performance requirements for spectroradiometer systems used to evaluate NVIS compatibility. Our OL 770-NVS and 770-NVS/NIR spectroradiometers not only meet...
