Alton仪器公司推出一种称为LM－30的通用光学万能表。这种仪器采用2048元的CCD线阵作为探测器。它能在200～1100nm波段内实时获取各种脉冲或者连续光源（例如发光二极管、激光二极管、可调激光器、灯管等）的光谱，其分辨率可达1nm。测得的光谱或者其它光学数据可显示在一个大 Alton Instruments introduced a universal optical multimeter called the LM-30. This instrument uses 2048 yuan CCD line array as a detector. It can obtain spectra of various pulsed or continuous light sources (such as LEDs, laser diodes, tunable lasers, lamps, etc.) in real time in the wavelength range of 200-1100 nm with a resolution of 1 nm. The measured spectrum or other optical data can be displayed in a large one
