極寬光譜SLD 高功率模塊(780-900nm高功率SLD模塊)
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 the highest output power with equal
intensity of spectral humps; different for different modules;
*** - describes spectral intensity dropout between spectral humps
**** - HP1-rated butterfly-packaged SLDs; more details upon request
The following part numbers should be used for ordering:
SLD-35(a)-(b)-(c)-(d)-(e)-XXX,
where:
(a) – 0 (free space) or 1 (fiber pigtailed),
(b) – power category, HP1, HP2 or HP3,
(c) – package type,
(d) – SM or PM (for fiber coupled modules),
(e) – PD (if PD monitor is required),
XXX – wavelength ( 825, 845, 865; a ±10-nm tolerance is guaranteed).
Example: SLD-351-HP1-DIL-SM-PD-825.
10-3 maximum feedback is allowed to run HP series SLDs safely at full
power. Models with reduced sensitivity to optical feedback are
available upon request. |
