极宽光谱SLD模块(790-890nm 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。

- PD-monitors
- FC/APC terminated pigtails
封装：
- fiber coupled: DIL, Butterfly
- free space: TOW
应用：

* TOW packaged SLDs;
† Current is specially adjusted to get the highest output power with equal
intensity of spectral lobes; different for different modules;
‡ Spectral Flatness parameter describes spectral intensity dropout between
spectral lobes;
** Pseudo-depolarized versions (light is launched into the fiber at 45 degrees
to the birefringent axes) are available upon request;
†† Butterfly packaged SLDs.
The following part numbers should be used for ordering:
SLD-35(a)-(b)-(c)-(d)-(e),
where:
a – 0 (free space) or 1 (fiber pigtailed),
b – power category (HP),
c – package type,
d – type of fiber, SM or PM (for fiber coupled modules),
e – PD (if a PD monitor is required).
Example: SLD-351-MP-DBUT-SM-PD.
