## Small and Thin Type of Gratings

The model numbers for Shimadzu's standard plane blazed holographic gratings are composed of code numbers that represent the groove density, blaze wavelength, and dimensions.

When ordering, specify the model numbers using the codes given in List1(for groove density and blaze wavelength, dimension)

(* Please put code numbers for dimensions in three square of code number. )

## List of dimensions (the code number with-xxx)

Width (W) × Height(H)  Code C
12.5×12.5 125
12.5×25.0 126
25.0×12.5 256
25.0×25.0 253

## Code Number Examples

Example1:
The code number for a grating with a groove density of 900 grooves/mm, a blaze wavelength of 400 nm, and dimensions of 25(W)×25(H)×3(T) is 090-040-253.
