Radiometers are used to measure the intensity of electromagnetic radiation (e.g., UVC, UVB, UVA, Vis, and IR).

UV sensors are designed to measure the power or intensity of incident ultraviolet (UV) radiation.

Solar radiation instruments measure the spectral range of radiation, including global solar radiation (sun + sky), net radiation (incoming solar - reflected solar) and the photosynthetic light spectrum.

UV light systems provide ultraviolet light for identification, tracing, curing, disinfection or processing applications.

Weather instruments are designed to measure one or multiple components of weather including wind speed and direction, rain or snow fall, solar radiation, temperature, pressure and humidity.

High intensity discharge lamps (HID) contain compact arc tubes, which enclose various gases and metal salts, operating at relatively high pressures and temperatures. HID lamps are often used as UV light sources.

Halogen lamps are high pressure incandescent lamps containing halogen gases such as iodine or bromine, which allow the filaments to be operated at higher temperatures and higher efficacies.

Incandescent lamps generate light by passing an electric current through a thin filament wire (usually of tungsten) until the wire is extremely hot.

Illuminators are used to provide adequate contrast for imaging. Illuminators include backlights, LED illuminators, and fiber optic illuminators.

Specialty or proprietary products and accessories related to lamps and light sources.

Infrared Sources are optoelectronic devices that emit infrared light.

Solar simulators and light sources produce a simulated solar spectrum for plant growth, material-degradation simulations, weathering tests for coatings, photovoltaic (PV) cell testing, sunblock evaluations, and window transmission studies.

Specialty testing and inspection services provide specialized or proprietary testing services and inspection services.

Lamps are light sources that emit incoherent light for illumination. There are many different types of products. Examples include fluorescent lamps, halogen lamps, heat lamps, incandescent lamps, LED lamps, projection lamps, spectral lamps, and stage lamps. Specialized and proprietary lamps are also available.
