摘要
PORS-15便携式光谱仪采用先进的平场凹面光栅作为分光器件,NMOS线性图象传感器作为接收器,配合外置紫外可见一体化光源,可同时测量200-800nm的全波段光谱,最短测量时间0.01s。通过RS232与微机通讯,由UVWin5.0软件读取测量图谱,可以进行图谱的数据处理及打印等操作,可独立完成光谱扫描、光度测量、定量测定及峰值检出等功能。独特的液晶触摸显示屏技术,将显示与输入集成,成为在同类仪器中体积最小,功能最全的仪器之一。可应用于环保、疾控、食品、医药等领域,特别适用于现场应急检测、在线监测、外出快速测量和野外地质勘探,具有广泛的应用前景。
PORS - 15 portable spectrophotometer uses fiat field concave grating NMOS linear image sensor as the receiver. Connected with outside ultraviolet - visible as the monochromator, and integrated light source, the instrument can measure spectrum wavelength from 200nm to 800nm. The shortest measure time is 0.01s. Connected with PC via RS232, the instrument can read measured spectrums, proceess data and print by using UVWIN5.0 software. It can perform spectrum scan, photometric measure, quantitative measure and peak- value detection etc. With unique LCD touching display, input and output are integrated. It has been one of the instruments with the least cubage and most functions, compared to the similar instruments. It like environment protection, disease control, foodstuff, medicine etc, especially suitable on - spot, online watch, outdoor quick measure and geological exploration. It is expected tion foreground. can be applied in field for emergency detecting to get a broad application foreground.
