LA120 Light Balancing Filter (Minus Blue)
Light Balancing Filter (Minus Blue) for machine-vision imaging — passes 400-700nm and blocks out-of-band light for repeatable contrast on the line.
Overview [ 01 ]
LA120 counteracts the ~120 mired color change created by traditional white LEDs (appearing very bluish in cast) as well as some similar xenon and metal halide lighting, while eliminating a large amount of the UV spectrum. Instead of using warm white LEDs, placing an LA120 filter over the camera lens and using cool white (blueish) LEDs results in the same apparent color, but a light head with higher intensity, longer life, and lower cost.
