Diffuse Reflectance Targets
Durable reflectance panels for laboratory and field applications that require exposure toharsh conditions
Typical 8O Hemispherical Reflectance - SRM-990

Spectralon® Contrast Targets
Spectralon Contrast Targets are perfect for thecalibration of video cameras, densitometers, thecontrast transfer of propagation media, and the testingof imaging systems in field conditions.
These chemically inert targets are durable andwashable, consisting of a diffuse white (99%reflectance) and a diffuse dark gray (10% reflectance)
panel mounted side-by-side in an anodized aluminum
frame.
Spectralon multi-step targets consist of four panels of99, 50, 25 and 12% reflectance values mounted sideby-side. The four panels provide equal optical density
differences and equal contrast between each adjacentpanel.

Infragold® Targets
Spectralon® Targets
Spectralon targets are ideal for laboratory and field applications that require longexposure to harsh environmental conditions such as field validation experiments
performed to collect remote sensing data. Because of the diffuse reflectanceproperties of Spectralon, these targets maintain a constant contrast over a widerange of lighting conditions.

Infragold® targets are mounted in an anodized
aluminum frame and are used for infrared applications.
Targets are available in plates up to 18 inches square.
Larger infrared targets can be constructed andcalibrated by arranging Infragold plates in arrays; seams
may be visible but do not affect the overall reflectanceof the target.

Spectralon targets are available in plates up to 24 inches square and are available
in white or gray material and are mounted in a rugged anodized aluminum frame.
Calibration data from 250 to 2500nm, every 50nm is supplied with the targets.
Calibration data is traceable to the National Institute of Standards and Technology(NIST). All targets are thermally and chemically stable and easily cleaned. Targets
larger than 24 inches squared can be constructed and calibrated, custom targetsof various reflectance values are also available up to 3 meters squared.
