All Sol-UV simulators spectral output are certified to be compliant to FDA CFR Part 201.327, ISO 24444:2019(E) Second Edition, ISO 24443:2021(E) Second Edition, and the International SPF Test Method (CTFASA/COLIPA/JCIA/CTFA: May 2006) for Spectral Match. With an optional filter, it can deliver JCIA UVA compliant output.

The irradiance uniformity over the work area is important to achieve and maintain. Hot spots can lead to errors in delivered dosage. The Sol-UV simulators spatial uniformity performance standard is designed to minimize hot spots and delivers less than 5% non uniformity across the entire work area. Spectral uniformity is also maintained over the work plane.
The Sol-UV housing provides a safe enclosure for the lamp. It is equipped with safety interlock systems to ensure operator and system safety. An integral fan(s) and filter blower provides forced air-cooling to maintain optimal lamp, optics and housing temperature. An Ozone free lamp is used to minimize exposure to ozone. The Oriel Sol-UV Simulator includes a shutter that is a rugged, single-blade shutter design specified for 1 million cycles. Real-world performance has exceeded 10 million cycles. The shutter has a minimum exposure time of 200 ms and can be controlled via a contact closure or logic level input, or a convenient push-button switch on the illuminator housing.
Temporal stability is also important in minimizing dosage errors. Oriel instruments experience in designing ultra stable power supplies provides that the output light is stable over time in order to ensure that the lamp fluctuations do not impact delivery of the erthemal dose desired. The typical drift over 24 hour is less than 2% (Max-Min) / (Max + Min), however this can be enhanced with our optional Digital Exposure System to substantially reduce lamp output fluctuations.
All Sol-UV model simulators are equipped with a Xenon arc lamp with output varied using the integrated variable attenuator aperture which provides the ability to vary the output from 10- 100% of the maximum available solar constants. The combination of lamp and filters produces the characteristic COLIPA/FDA/ISO compliant output. The average lamp life during which the system maintains spectral compliance is 1000 hours. The filters utilized require no maintenance. Replacement filters in the event a filter is broken, are sold separately.
The highly regulated power supply provides constant electrical power to the Xenon lamp. Lamp usage can be monitored in accumulated hours from the power supply. It is important to replace the lamp at the end of its rated life to maintain appropriate spectral match. The lamp’s output and spectral match can not be assured with continued use beyond the specified lifetime (@1000 hours).
A Variable Aperture feature is integrated into all Sol-UV simulators that provides user variable partial sun illumination capability. The range of attenuation is 10 - 100% of the maximum available solar constants. The simple-to-use dial control provides infinite control of attenuation. Spectral performance and temporal stability are maintained at any attenuation.
There are three UVA filter sets that can be used with the Sol-UV series simulators. All simulators include filter set SOL-UV-A-F, typical response shown, which is used to meet the applicable standards. Two additional filters can be utilized to modify the UVA spectral output, with cut-on wavelengths at 340 or 360 nm. Other UV filters can be installed, but performance specifications cannot be guaranteed.
The SOL-UV series simulators are ideal for SPF testing (in-vivo or in-vitro), Photo-Toxicity Testing, Photo-Allergy Testing, Photo-Carcinogenicity Testing, or Photo-Genotoxicity Testing applications.
Oriel SOL-UV series maintain compliance during the rated "performance lifetime" of the lamp. Extended warranties and installation service are available for these models. Contact Newport Sales for further information.
Arc lamps may emit dangerous levels of UV radiation depending on their source type. Ensure that only authorized personnel are in the vicinity of the source, and wearing the necessary safety equipment such as UV protective eyewear, clothing, and gloves. Lighted UV warning signs, posted outside laboratory doors where UV sources are operating, can prevent accidental exposure. Newport also recommends using an electronic shutter to block the beam when the source is not in use but remains turned on. Alternatively, the beam can be safely contained by using beam tubes or fiber optic cables to deliver the light to a sample. It is recommended to vent the ozone that is produced by some lamp models to the outside or use an Ozone Eater.
Getting any solar simulator up and running is a straightforward process, as demonstrated in this video.
