The sun and solar simulators have a broad output ranging from UVB into the IR. The bands of interest include UVB, UV-Vis and NIR.
UVB is a band of ultraviolet radiation with wavelengths from 280-315 nanometers produced by the Sun. UVB refers to a specific portion of the sun’s energy reaching the earth’s surface.
This type of radiation accounts for only a small portion of the electromagnetic spectrum, but it has an unusually large photo-biological effect. Both plants and animals are affected by increases in UVB radiation.
UV radiation plays a role in the degradation of all polymeric materials as well as biological systems. It also acts as a germicide, a fungicide, and a bactericide in agriculture and biological systems.
UVB radiation is responsible for a wide range of damaging human and animal health effects, primarily related to the skin (skin cancers), eyes (cataracts), and the immune system. Possible eye damage can result from high doses of UV light, particularly to the cornea which easily absorbs UV light.
UVA/Vis, though much less hazardous, also contributes to degradation and skin and eye hazard.
Another contributor is the infrared (IR). IR is known to cause serious damage to the eyes, in particular the retina and the cornea.
ILT offers specialized systems for testing Solar UVB with a billion-to-one Vis/IR rejection. This is critical for testing Solar UVB since nearly all of the sun's energy is in the longer wavelengths. Using the same radiometers included with the solar UVB system, different detectors, filters, optics and calibrations can be ordered for testing UVA, Vis, NIR and IR.
Also, a special solar radiation measurement system is available for use in MIL-STD-810G, Test Method 505.5 Solar Radiation (Sunshine). See last entry in the table below - please contact ILT Sales for system details and pricing.
Use the table below to identify the system (meter + detector) that meets your specific application. Use the table to find the spectral range you wish to measure. The table can be filtered to show our meters by type, (e.g., hand-held), as well as searching on the minimum and maximum spectral range you wish to measure. The tables can also be sorted to group systems by meter type, spectral range, measurement range, and units. Click the product link of the system to view it's details.
