970nm SLD模块(SLD模块)
我们的主要产品是波长从650nm到1620nm具有不同谱带的单模尾纤SLD模块。
我们正在为不同的应用制造制冷(有制冷器和电热调节器)和非制冷的模块，像光纤陀螺仪、OCT、光纤组件测试、光计量学和大量的其它模块。我们也提供自由空间模块，特别是用于原子力显微术，但也包括无斑纹照明、白光干涉测量、光学试验和测量以及其它模块。

1-2 mW ex SM fiber – contact us for more details
Following marking should be used for ORDERING:
SLD-48(a)-MP-(c)-(d)-(e)
Where:
a = 0 (free space) or 1 (fiber pigtailed)
c = package type
d = SM (isotropic) or PM (polarization maintain) fiber (pigtailed versions only)
e = PD (if PD monitor is required)
Example: SLD-481-MP-DIL-SM-PD
