Used for image sensors! A luminance box that guarantees high precision in brightness (luminance), color (color temperature), uniformity, and more within the emission surface.
The "LSB-1010FB-CRI" is a culmination of the technology we have developed so far and can be considered a standard brightness box. In addition to the high uniformity of brightness and high color rendering required for brightness boxes, it is also equipped with a user interface that allows for more intuitive operation. 【Features】 ■ Uses high color rendering LEDs Ra=97 ■ DC lighting with no flicker for high uniformity across the surface ■ Allows for arbitrary frequency lighting using pulse mode, reproducing lighting environments affected by voltage flicker ■ Brightness adjustment is possible ■ Two systems for color temperature settings ■ Automatic brightness calibration ■ Numerous options and customizations available *For more details, please contact us or download the PDF materials.
