HEXAGON-IMAGING-PAM是德国WALZ公司新推出的大型蜂巢矩阵叶绿素荧光成像系统。它凭借高精度的脉冲振幅调制(PAM)技术,可以对20×24cm的区域进行成像。分辨率高达1.2 MP(1000 x 1200 px, 2x2 binning技术,实际是2000×2400),像素尺寸3.45 x 3.45 µm

超高分辨率的基础是成像区域光场的均匀性,在设计过程中,光源阵列中LED的位置是经过精心布局的,以保证测量区域内无阴影,所有成像区域内的样品均匀照光,样品间的差异可以尽收眼底。大功率LED面板的冷却效果非常好,可以大限度的延长LED的使用寿命。

增加远红光(FR)LED 面板,可用于测量所研究样品的Fo'值。

HEXAGON-IMAGING-PAM采用蜂巢矩阵式LED面板拼接技术,单个六边形蜂巢矩阵单元之间LED的不平横可以独立补偿,初衷是为实现样品区域的理想照明提供更优的选择。

尽管成像区域很大,但是它依然足够灵活,可以测量各种类型的样品,如盆栽植物,穴盘中培养的植物,培养皿上的植物或多孔板中的藻类悬浮液。

滑动门设计,集成安全关闭功能,开门状态下,饱和脉冲的强度会被抑制以保护操作人员的眼睛。

l 突变株筛选功能:可跟据成像结果快速筛选光合、产氢/油、抗逆(抗盐、抗旱、抗病等)等突变株。

l 微藻毒理研究功能:可同时测量496孔板,即384个微藻样品(对照和处理组)的光合活性,软件自动给出处理组样品相对于对照组的光合抑制百分比。
