  • OPT4048: OPT4048和OPT4060光学传感器 光谱曲线失真问题

    已解决
    Part Number: OPT4048 Other Parts Discussed in Thread: OPT4060 我们测量了OPT4048和OPT4060光学传感器，发现OPT4048的光学响应曲线与CIE1931-XYZ曲线比例差别巨大，尤其是在蓝光LED照射OPT4048时，XYZ比例更接近OPT4060的RGB比例， 我想问的是，OPT4080的光谱曲线是否按照官方datasheet标称那么接近CIE9131-XYZ？或者是我的驱动程序问题或者是买的两款芯片都是OPT4060
