我們的主要產品是波長從650nm到1620nm具有不同譜帶的單模尾纖SLD模塊。
我們正在為不同的應用制造制冷(有制冷器和電熱調節(jié)器)和非制冷的模塊，像光纖陀螺儀、OCT、光纖組件測試、光計量學和大量的其它模塊。我們也提供自由空間模塊，特別是用于原子力顯微術，但也包括無斑紋照明、白光干涉測量、光學試驗和測量以及其它模塊。

Following marking should be used for ORDERING:
SLD-561-(b)-(c)-(d)-(e)
Where:
b = power category (MP1...MP3)
c = package type
d = SM (isotropic) or PM (polarization maintain) fiber (pigtailed versions only)
e = PD (if PD monitor is required)
Example: SLD-561-MP2-DBUT-SM |
