Grating Selection
H1034 monochromator can be built with several grating choices that all have the same parameters such as curvature, groove density, correction of the aberrations, angle of deviation, and more.
What differs among them is the blazed wavelength.

|---|---|---|---|---|---|
|
Aberration-corrected Concave Holographic Grating |
250 nm (covering 185-1,000 nm) |
350 nm (covering 185-1,000 nm) |
500 nm (covering 300-1,000 nm) |
570 nm (covering 350-1,000 nm) |
|
| Groove Density | 1,200 (gr/mm) | ||||
| F/# | F/2.8 | ||||
| Dimension | 38 mm x 38 mm and 42.4 x 42.4 (± 0.1) mm | ||||
| Input/output angle of deviation | 34.7° | ||||
