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-34-HP
特征：
- very wide bell-shaped optical spectrum
- no sidelobes in the coherence function
- negligible residual Fabry-Perot modulation depth
- internal PD monitor
- FC/APC terminated pigtails
封装：
- fiber coupled – Butterfly, DIL
- free space – TOW
应用：
- high resolution OCT
- fiber sensors
- Bragg grating sensors
- optical measurements
Additional and customized:
- PM pigtails (slow axis alignment; 45 degree orientation upon request)
- 4-mW SMF model with reduced sensitivity to feedback

* Pseudo-depolarized versions (light is launched into the fiber with its
polarization oriented at 45° to the birefringent axes) are available upon request
The following part numbers should be used for ordering:
SLD-34(a)-(b)-(c)-(d)-(e)-(f),
where: a – 0 (free space) or 1 (fiber pigtailed),
b – power category (HP1, HP2), c – package type,
d – SM (isotropic) or PM (polarization maintaining) fiber (pigtailed versions only),
e – PD (if PD monitor is required), f – central wavelength.
Example: SLD-341-HP2-DBUT-SM-PD-840.
A maximum feedback of 10-3 is allowed to run HP series SLDs safely at full power. |
