产 品 说 明
840nm自由空间输出SLD光源模块/自由空间输出SLD模块
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-380-MP
特征：
- Spatial brightness comparable to that of laser diodes
- Flat spectrum (comparable to that of LEDs) with negligible residual
Fabry-Perot modulation depth
- Spectral ripple of 2% or less
- maximum parasitic secondary coherence subpeaks of -20 dB (10log)
- higher power versions (up to 50 mW and more at +25 °C) are available upon request
封装：
TO9 Package*
* Free-space SLD modules in temperature stabilized packages (like TOW1,2 or TO3 with internal TEC and thermistor for SLD temperature stabilization) are available upon request.
应用：
- atomic force microscopy
- optical coherence tomography
- optical sensors
- optical measurements
- others

*** 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
