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;
** Pseudo-depolarized versions (light is launched into the fiber with its
polarization oriented at 45° to the birefringent axes) are available upon request;
†† Butterfly packaged SLDs.
Note: SLD spectra for the batches in stock are available upon request.
The following part numbers should be used when ordering:
SLD-33(a)-(b)-(c)-(d)-(e),
where: a – 0 (free space) or 1 (fiber pigtailed);
b – power category HP1, HP2 or HP3; c – package type;
d – SM or PM (fiber coupled modules); e – PD (if PD monitor is required).
Example: SLD-331-HP1-DIL-SM-PD.
A maximum feedback of 10−3 is allowed to run HP SLDs safely at full
power.
