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。

* TOW packaged SLDs;
** current is specially adjusted to get highest output power with equal
intensity of spectral lobes; different for different modules;
*** Spectral Flatness parameter describes spectral intensity dropout
between spectral lobes;
**** Lyot depolarized versions are available upon request;
***** Butterfly packaged SLDs
Very broad 100 nm FWHM spectrum SLDs are available upon request!
Following marking should be used for ORDERING:
SLD-47(a)-(b)-(c)-(d)-(e)
Where:
a = 0 (free space) or 1 (fiber pigtailed)
b = power category HP1 or HP2
c = package type
d = SM or PM (fiber coupled modules)
e = PD (if PD monitor is required)
Example: SLD-471-HP1-DIL-SM-PD
10-3 maximum feedback is allowed to run HP series SLDs safely at full power.
