Q: How did Hitachi establish its advanced grating technology? There are currently two main ways to produce diffracting gratings. One is to use holographic technology that takes advantages ...

The solution was then cast on a holographic diffraction-grating master mould to obtain free-standing silk gratings with a grating pitch of 600 grooves per millimetre, as shown in Fig. 4.

Description: The 33010FL01-310H Plane Holographic Reflection Grating has 1800 grooves per millimeter and a nominal blaze wavelength at 300 nm. It has a recommended spectral region of 200 to 900 nm.

As a rule, first order diffracted beam efficiency decreases by 50% at 0.66 and 1.5 times the blaze wavelength. No grating can diffract a wavelength greater than two times the groove period. By ...
