产 品 说 明
840nm-860nm宽带超辐射发光二极管/超辐射发光二极管宽带光源模块
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。

* Pseudo-depolarized versions (light is launched into the fiber with its
polarization oriented at 45° to the birefringent axes) are available upon request
The following part numbers should be used for ordering:
SLD-34(a)-(b)-(c)-(d)-(e)-(f),
where:
a – 0 (free space) or 1 (fiber pigtailed),
b – power category (MP1, MP2), c – package type,
d – SM (isotropic) or PM (polarization maintaining) fiber (pigtailed versions
only),
e – PD (if PD monitor is required), f – central wavelength.
Example: SLD-341-MP1-DBUT-SM-PD-840.
