SLD高功率宽带光源模块(800-870 nm高功率宽带SLD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。

* 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

 

SLD modules with similar outgoing parameters are available

at median wavelength 800 nm and 880 nm.

 

Following marking should be used for ORDERING:

SLD-37(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-371-HP1-DIL-SM-PD

 

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