SM/PM 光纤耦合SLD模块(770-890nm中等功率光纤耦合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。

* Maximum output power is guaranteed at a forward current of 160 mA or less.
** 830-nm wavelength is not guaranteed if it is not mentioned in the order. See
part numbers below.
*** Residual spectral modulation depth and secondary coherence subpeaks are
specified at an output power of 1.5 mW ex fiber.
**** Case temperature (depends on package style). The specification shown is
the case temperature for butterfly-packaged modules.
Additional and customized:
- wider spectrum, higher power, lower spectral ripple for meeting
customer requirements—see the next page for performance examples;
- FC/APC terminated pigtails;
- PM fiber coupled, polarized or pseudo-depolarized (light is launched into
the fiber at 45 degrees to the birefringent axes) versions.
The following part numbers should be used for ordering:
SLD-381-MP-(c)-(d)-PD-XXX,
where:
c – package type, DIL14, DBUT(butterfly) or SBUT (semi-butterfly),
d – type of fiber, SM (isotropic) or PM (polarization maintaining),
XXX – wavelength (in nanometers).
Example: SLD-381-MP-DIL-SM-PD-830.
Attention: center wavelength is guaranteed with a tolerance of maximum ±10 nm. If
a closer tolerance is required, contact our company before placing the order. If the
center wavelength is not explicitly specified in the order, an SLD centered at any
wavelength within the range of 830±20 nm may be shipped.
