670nm光纤耦合SLD模块/670nm 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-261-MP

 

特征：

- visible 670 nm band SM fiber coupled SLD modules

- flat spectrum with negligible residual Fabry-Perot modulation depth

- maximum parasitic secondary coherence subpeaks intensity below -20 dB (10 log), maximum below -30 dB upon request

 

应用：

- atomic force microscopy

- optical sensors

- optical coherence tomography

- optical measurements

- others

 

封装：

- fiber coupled – DIL, Butterfly; uncooled “minibut” packages available upon request

* It is not allowed to exceed maximum output power or maximum drive

current, whatever happens first

** Center wavelength 670 nm is not guaranteed. Contact Company

representative if you require a tighter tolerance of center wavelength.

*** Rated at minimum power, not guaranteed at maximum power of a

particular power category

**** Pseudo-depolarized versions (light is launched into the fiber at 45 degrees

to the birefringent axes) are available upon request

***** Butterfly packaged SLDs

 

Additional & customized:

- FC/APC termination of fiber pigtail

The following part numbers should be used for ordering:

SLD-261-MP(a)-(b)-(c)-PD,

where:

a – power category (MP1 or MP2),

b – package type (DIL, DBUT, SBUT),

c – type of fiber — SM (isotropic) or PM (polarization maintain).

Example: SLD-261-MP1-DIL-SM-PD.
