These are planar gratings prepared by means of a precision ruling engine with a diamond cutting tool. Gratings can be ruled on a variety of substrates; for example, glass, metal and ceramic. Groove density ranges from 20 to 1800 grooves/mm. This is the preferred type of grating for the infrared (IR) because of the relatively large spaces between grooves. In this case, there is better control over blaze shape and defects are small relative to the size of the spacing.RULED PLANE GRATINGS
The table below lists the range of plane ruled gratings available from HORIBA Jobin Yvon.
The last three digits of the reference number indicate the size of the grating. Select these digits from the Size Table that appears just after the following table and replace the X's in the latter table with the digits.
Typically the usable efficiency range of a ruled grating can be approximately calculated as 2/3 x optimal wavelength to 2 x optimal wavelength.
Ruled gratings are available in sizes up to 120 mm x 140 mm except 1800 g/mm (up to 90 mm x 90 mm) and 1200 g/mm (up to 110 mm x 110 mm).
