970nm SLD模块(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-48-MP

 

特征：

- low cost medium power modules at 970 nm

- flat spectrum with negligible residual Fabry-Perot modulation depth

- maximum -20 dB secondary coherence subpeaks, -30 dB max upon request.

 

封装：

- fiber coupled: DIL, Butterfly

- free space: TOW

 

应用：

- fiberoptic sensors

- optical coherence tomography

- optical measurements

 

Additional & customized:

- PD - monitors

- FC/APC terminated pigtails

- PM pigtails (polarized or Lyot depolarized output)

Following marking should be used for ORDERING:

 

SLD-48(a)-MP-(c)-(d)-(e)

Where:

a = 0 (free space) or 1 (fiber pigtailed)

c = package type

d = SM (isotropic) or PM (polarization maintain) fiber (pigtailed versions only)

e = PD (if PD monitor is required)
