If your application doesn't require the highest level of uniformity of illumination, a Class ABB system may work for you. Class ABB systems still provide the highest spectral match performance (Class A) as defined by the most recent standards from the IEC, JIS and ASTM. Although the uniformity is Class B (based on the IEC testing protocols), these Class ABB systems may have better uniformity than competitive simulators that claim Class A uniformity to only the current ASTM standard, or are measuring it according to the older IEC, JIS and ASTM standards. The Class ABB systems provide a cost effective option that provides you durable Oriel Solar simulator, the name you have trusted for 40years as a quality supplier backing their products utilizing the worldwide Newport network of resources. An optional light intensity controller can be purchased to bring stability to Class A if it becomes necessary in the future.
