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。

* 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.
