CTFASA/COLIPA/JCIA/CTFA/FDA/ISO Compliant
Independent third party lab certified for compliance
Variable Output (10-100%) of max available Solar Constants
5% Uniformity of irradiance over the entire work plane
Designed for Photo-Biology Applications
With over 40 years of experience in building solar simulator products for PV applications, Newport Corporation’s Oriel® Sol-UV™ take solar simulation into demanding applications in photobiology. All Oriel SOL-UV simulators incorporate a patent pending design that provides standards compliant UV light ouput with non-Uniformity of Irradiance <5% over the entire sampling area. Output power can be varied from 10 - 100% of the maximum available solar constants using the unique integrated attenuating device. All Oriel Sol UV simulators uses a black non-reflective finish to minimize stray light. Safety interlocks prevent inadvertent exposure to UV light. Oriel Sol-UV simulators rugged design is backed by the Newport Corporation\'s world wide organization. These large area UV sources use a xenon lamp and proprietary filters to meet, efficiently and reliably, all performance parameters. The result is a cost-effective system designed for laboratory or production environments – all backed by our global service and support network.
All Sol-UV simulators spectral output are certified to be compliant to FDA CFR Part 201.327, ISO 24444:2010(e) First Edition, and the International;l SPF Test Method (CTFASA/COLIPA/JCIA/CTFA: May 2006 for Spectral Match. With an optional filter, it can deliver JCIA UVA compliant output.

Colipa Irradiance Response Curve
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.
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 24hour is less than 2% (Max-Min) / (Max + Min)
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.
Integrated Shutter
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.
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 borken, 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).

In order to facilitate the measurements and adjustments necessary to maintain spatial uniformity, Oriel has developed a manual uniformity measurement tool to allow rapid measurement and determination of performance. The use of these tools allows you to maintain the Oriel Sol-UV simulator within stated performance specifications. * Please contact a Sales Engineer for details.
