TDLAS100
Designed for butterfly package diode lasers with working current < 120mA. These lasers are commonly found in visible to near infared range (Nanoplus, Eblana, etc). This controller box include digital modulation-demodulation, current driving, temperature control and variable gain amplifier. All functions are PC controlled. (Note: laser are not included)
产品信息
可调谐半导体激光吸收光谱 (TDLAS) 是应用于气态分子检测的新一代光学技术，具备灵敏度高，特异性好，抗干扰能力强，寿命长等特点。
以往实验中，需要很多不同设备的组合才能实现该技术。瑞荧仪器的集成激光模块则提供了一套完整的解决方案实现：它集成了激光正弦驱动、斜率扫描、温度控制、散热、可变增益放大、数字一倍和二倍频解调， 甚至集成了一套吸收峰提取算法。后续只需要将激光引入测量光路中，并将探测器信号接入模块，即可开始实验，极大降低了该技术的入门难度。模块带有开放的通讯协议，便于您将其集成入自己的设备中。
该系列由不同型号，对应不同激光功率，支持近红外波段常用蝶形激光器，红外量子级联激光器等不同激光。
