Thermal Handheld Emissometer

The ET-100 measures directional reflectance at six bands in the thermal infrared spectral region at two incidence angles, 20° and 60°. Based on those values, directional and total hemispherical emissivity is calculated. It is a real portable battery powered reflectometer controlled by a built in PDA type computer. The ET-100 is a handy tool for radiative heat transfer applications including field inspections.

DHR Directional Hemispherical Reflectometer

SOC-410 - Surface Optics Corporation

The SOC-410 Directional Hemispherical Reflectometer is the first of its class handheld reflectometer for quick and accurate measurements of optical constants of surfaces in the infrared spectral region. It is the only fully portable hand-held device for quick inspection of coatings and materials in the field. The DHR head measures the optical constants of materials for six spectral regions.

In-Band Handheld Emissometer

ET-10 - Surface Optics Corporation

The ET-10 answers the long standing need for the measurement of emissivity as an entry parameter for infrared cameras involved in measurements of temperature. Advanced infrared cameras require the input of an emissivity value for accurate temperature calculations. The emissivity values obtained from tables can be far from real, leading to large temperature uncertainties.

Visible / NIR Portable Reflectometer

410-Solar - Surface Optics Corporation

The 410-Solar is a battery operated portable reflectometer, the ideal tool for field solar reflectance, solar absorbtance measurements and mirror assessment. Quickly and accurately collects solar reflectivity data necessary to calculate solar reflectance index (SRI) values for cool roofing and green building LEED certification. The SOC410-Solar conforms to ASTM E903, the standard test method for solar absorptance, reflectance, and transmittance of materials.

410-Vis-IR - Surface Optics Corporation

The 410 Vis-IR has been developed as a modern replacement for the classic Gier Dunkle DB100 reflectometer. The 410 Vis-IR measures total reflectance at combined 13 spectral bands. The Vis head operates from 335 nm to 2500 nm, and the IR head operates from 1.5 microns to far IR. The reflectances in the bands are converted to spectral information. Solar irradiance function or blackbody function is applied to calculate solar absorptance or thermal emissivity for two angles 20 and 60 degrees. Hemispherical total emissivity is predicted based on calculated directional emissivity.
