Solar Light's new specialty line of HEV Solar Simulators are designed specifically for professional research in the High Energy Visible spectra. These state of the art single output HEV Solar Simulators produce solar radiation in the 400-500nm range, or that portion of the visible light spectrum that is closest to the UV band - mainly violet and blue light rays. In addition to the HEV output, they can be quickly and easily configured by the end user to provide UVA only, UVB only, UVA+B, or full spectrum sunlight optionally. Custom spectra are also available. These units are specifically designed for in vitro and in vivo clinical, medical, and photobiological studies including SPF, oxidative stress, hyperpigmentation, age spots, and melasma. Our LS1000 Models are available with 1000W output, in round or square beam sizes ranging from 5cm to 15.25cm, in compliance with laboratory standards such as ASTM, IEC, and ISO. They come complete with everything required to begin testing immediately, including Solar Simulators, Power Supplies, Automatic Dose Controllers, NIST-Traceable PMA-Series Sensors, safety glasses, and other related accessories.
