摘要 | PURPOSE:To obtain a stable laser emitting beam irrespective of a variation in an external environmental temperature by providing a heating/cooling element for holding the interior of a case at a predetermined temperature and a temperature detector. CONSTITUTION:A peltier element 6 is provided as a heating/cooling element between the joint 3c of a stationary base 3 and its heat sink 7. A thermocouple 8 is provided as a temperature detector in contact with part of the base 3. The input/output terminals of the element 6 are led through a terminal 9b, and the thermocouple 8 is externally led through a terminal 9c, and the terminals 9b, 9c and the terminal 9a of the laser 1 are attached through insulators to a stem 4. When the detected temperature is lower than a set temperature by a temperature regulator, the element 6 is operated as a heating element, while when the detected temperature is higher than a set temperature, it is operated as a cooling element. Accordingly, the temperature in a cap 5 is so regulated as to become the set temperature on the basis of the output signal of the thermocouple 8. Thus, stable optical characteristics are held. |
其他摘要 | 用途:通过提供用于将壳体内部保持在预定温度的加热/冷却元件和温度检测器,以获得稳定的激光发射光束,而不考虑外部环境温度的变化。组成:在固定底座3的接头3c和它的散热器7之间提供一个珀耳帖元件6作为加热/冷却元件。热电偶8作为温度检测器提供,与基座3的一部分接触。输入/元件6的输出端子通过端子9b引出,热电偶8通过端子9c从外部引出,激光器1的端子9b,9c和端子9a通过绝缘体连接到杆4上。通过温度调节器检测温度低于设定温度,元件6作为加热元件操作,而当检测温度高于设定温度时,它作为冷却元件操作。因此,根据热电偶8的输出信号调节盖5中的温度以使其成为设定温度。因此,保持了稳定的光学特性。 |
