KolaDeep™ 光谱测量系统:测量更深的阻挡

作者 IDEX Health & Science

新的基于荧光的生命科学和生物医学仪器越来越多,需要具有非常高的阻挡(OD)和陡峭的光谱边缘的好的滤光片,其在高透射和高OD之间转换。因此,我们 IDEX Health & Science 的 Semrock 工程师开发了 Kola Deep™ 光谱测量系统(SMS),这是一个专有的获过奖的平台,用于对我们的滤光片的陡和深的光谱特性进行经验证的测量。该系统用于日常生产,使由这些滤光片制成的仪器能够达到预期性能。

Kola Deep™ 光谱测量系统的功能包括::

  • KolaDeep™ 在紫外、可见光和近红外范围内的波长范围内测量 OD 8-9 的阻挡,以及 OD 11的光谱特征。
  • KolaDeep™ 解决了测量难题:从 90% 透射到 OD>7 的边缘波长大于0.2%的边缘。

上图显示了在定制五带滤光片上测量的 OD 。通带之间的阻挡规定为OD 8 以上,以减少激发光泄漏。理论和测量结果均符合 OD>8,OD>9 至噪声基底的部分阻挡。

我们的工程团队对 KolaDeep™ 进行了广泛的鉴定测试,以表征和确认系统的波长和光度精度。

白皮书“IDEX Health & Science Semrock 的高级光谱测量系统”介绍了 Semrock 的六个样本和分析基于 KolaDeep™ SMS 测量的滤光片,这里显示了一些。

KolaDeep™ SMS 在 UV 和 NIR 光谱范围内表现良好。1064 nm Semrock MaxLine® 激光线消杂滤光片的示例如下所示。测量值(红色)确认所需的阻挡,并与理论设计(绿色)一致,OD>7。来自高级商用系统的数据(蓝色)在 OD 3 以上不准确。
