Low Stray Light Diffraction Gratings [Lo-Ray-Ligh®]
Low Stray Light Diffraction Gratings
Features
LO-RAY-LIGH® has guaranteed values of stray light at the intermediate position between zero-order and + first-order lights. The values are measured by Shimadzu's laser stray-light-measuring system.
1. Low Stray Light Values
The stray light values are at less than half of conventional gratings.

2. Vicinity of First-Order Light
The light intensity at vicinity of first-order light of LO-RAY-LIGH® looks like a profile as if being the silhouette of the mermaid line into the deep sea.

3. Relative Diffraction efficiency
LO-RAY-LIGH® is high efficient.


* These relative diffraction efficiency data are not the guaranteed values but representative ones.
