SLD宽带光源模块(1000 nm and 1020 nm SLD宽带光源模块)

 

 

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。

* Pseudo-depolarized versions (light is launched into the fiber with its

polarization oriented at 45° to the birefringent axes) are available upon request

 

The following part numbers should be used for ordering:

 

SLD-52(a)-(b)-(c)-(d)-(e)-(f),

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

b – power category (MP, HP), c – package type,

d – SM (isotropic) or PM (polarization maintaining) fiber (pigtailed

versions only), e – PD (if PD monitor is required),

f – central wavelength.

Example: SLD-521-HP2-DBUT-SM-PD-1020 or

SLD-521-HP1-DBUT-SM-PD-1000.

 

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