极宽光谱SLD高功率模块(780-900nm高功率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。

* - TOW-packaged SLDs;

** - current is specially adjusted to get the highest output power with equal

intensity of spectral humps; different for different modules;

*** - describes spectral intensity dropout between spectral humps

**** - HP1-rated butterfly-packaged SLDs; more details upon request

 

The following part numbers should be used for ordering:

SLD-35(a)-(b)-(c)-(d)-(e)-XXX,

where:

(a) – 0 (free space) or 1 (fiber pigtailed),

(b) – power category, HP1, HP2 or HP3,

(c) – package type,

(d) – SM or PM (for fiber coupled modules),

(e) – PD (if PD monitor is required),

XXX – wavelength ( 825, 845, 865; a ±10-nm tolerance is guaranteed).

 

Example: SLD-351-HP1-DIL-SM-PD-825.

 

10-3 maximum feedback is allowed to run HP series SLDs safely at full

power. Models with reduced sensitivity to optical feedback are

available upon request.
