极宽光谱SLD模块(790-890nm 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。

Model number：SLD-35-MP

特征：

- very wide optical spectrum

- short coherence length

- negligible residual Fabry-Perot modulation depth

- SM or PM pigtails (polarized or pseudo-depolarized output emission ex PM fiber)

- PD-monitors

- FC/APC terminated pigtails

 

封装：

- fiber coupled: DIL, Butterfly

- free space: TOW

 

应用：

- ultra-high resolution OCT

- Bragg grating sensors

- fiber sensors

- optical measurements

* TOW packaged SLDs;

† Current is specially adjusted to get the 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 at 45 degrees

to the birefringent axes) are available upon request;

†† Butterfly packaged SLDs.

 

The following part numbers should be used for ordering:

 

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

where:

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

b – power category (HP),

c – package type,

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

e – PD (if a PD monitor is required).

 

Example: SLD-351-MP-DBUT-SM-PD.
