1m plane grating spectrographic 31W ,focus distance 1050mm, working wave 200-850mm, grating lines 1200/mm

31W IA 1M grating spectrograph

1. Use:

This instrument uses planar reflection grating to study the composition and content of the material, mainly used for the daily qualitative and quantitative analysis of metal alloy (including mineral mine stone), the identification of impurities of pure metal and material, and various accessories, used for laser micro-area analysis, recording flash and weak light phenomenon.
