| The
simplest monochromator in the world has a Type IV aberration-corrected
concave hologrphic grating. |
 |
Specifications
3 versions available - UV-V, V and V-IR. Gratings are not
interchangeable. Aberration corrected concave gratings with
no internal mirrors ie single optical element for maximum
throughput.
