840nm 自由空間輸出SLD光源模塊/自由空間輸出SLD模塊
我們的主要產(chǎn)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(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。

* Maximum output power is guaranteed at a forward current of 160 mA or less.
** SLDs at other center wavelengths, for example, 790±10 nm, are available
upon request
*** Measured at output power of 10 mW
**** In percent of the value of output power at +25 °C. Typical value for output
power is 5–20 mW at +25 °C. Note: operation at high temperature accelerates
aging and reduces lifetime
