我們的主要產(chǎn)品是波長(zhǎng)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(yīng)用制造制冷(有制冷器和電熱調(diào)節(jié)器)和非制冷的模塊，像光纖陀螺儀、OCT、光纖組件測(cè)試、光計(jì)量學(xué)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(shù)，但也包括無(wú)斑紋照明、白光干涉測(cè)量、光學(xué)試驗(yàn)和測(cè)量以及其它模塊。

* TOW packaged SLDs;
** current is specially adjusted to get highest output power with equal
intensity of spectral lobes; different for different modules;
*** Spectral Flatness parameter describes spectral intensity dropout
between spectral lobes;
**** Lyot depolarized versions are available upon request;
***** Butterfly packaged SLDs
Following marking should be used for ORDERING:
SLD-47(a)-MP-(c)-(d)-(e)
Where:
a = 0 (free space) or 1 (fiber pigtailed)
c = package type
d = SM or PM (fiber coupled modules)
e = PD (if PD monitor is required)
Example: SLD-471-MP-DIL-SM-PD
