This is for a 16-unit set of LASI, designed to illuminate up to a 2x2m target with excellent three dimensional uniformity. All LASI systems operate with Xe arc lamps and therefore with the solar color temperature of 6,000 K. This allows the LASI to be used in applications that vary with depth, as opposed to generating only 2D uniformity on a single plane.This price does include a basic frame to hold the LASI at the correct distance from the target plane.This device is capable of Class B spectral compliance and Class B temporal instability.Uniformity over the entire target area is typically 15%. The overlap between units is an essential part of creating better spatial uniformity, and this unit can achieve ASTM Class C spatial uniformity within the central area, excluding the 1/4 m area around the perimeter. This meets ASTM criteria for Class BCB solar simulators.Each unit requires 220VAC/10A.Better performance is possible; please discuss your particular needs with your authorized Sciencetech technical support staff member.
