The White Balance Reflectance Targets can be used for a variety of applications including calibration of imaging systems, back light illumination, laser targets, and optical reflectors. Such targets are important in determining the correlation between an input and output quantity for measurement devices. These targets are 99% reflective throughout UV-VIS-NIR wavelengths. This known input value is used to evaluate the correlation between the output values of an instrument, such as a camera, and the known values of the standard. The differences provide calibration correction factors, which allow the instrument to take absolute readings.
In the case of color reproduction of an imaging system, using the target can provide true color under any lighting conditions. In most color cameras, calculating the differences between input and output and applying correction factors is done automatically by the camera’s "white balance" function. This makes the standard very easy to use. If a camera does not have an automatic white balance, color management can be done manually. Besides calibrating for color, the standard can be used for calibrating lighting levels and uniformity within an imaging system.
All targets are durable, chemically inert, and washable. They are ideal for applications that require long exposure to harsh environmental conditions, which makes them ideal for many machine vision and outdoor environments. All targets come framed in an anodized aluminum housing with mounting holes for easy integration. Targets include tested calibration data from 250 to 2500nm every 50nm.
Note: Custom targets are recommended if the FOV is less than 0.64mm.
