Guaranteed backlight light source with brightness and brightness uniformity.
This is a diffusion surface light source that guarantees brightness (luminance), uniformity within the emission surface, and color tone (color temperature). The "Model: LSB-1010 series" allows for significant variations in luminance and color temperature, with high adjustment resolution. The "Model: VLB-10, 1411, 3020 series" has a compact housing size and can accommodate large emission surfaces. These can be used for development research purposes, production lines, and equipment integration. Regarding wavelength, there are high color rendering white LEDs with smooth spectral changes, and models that support near-ultraviolet and near-infrared up to 2000nm are also available.
