[To all users]

• Versatile diffraction grating slide with three types of slit (single slit, double slit and diffraction grating slit) on a substrate.

[To teachers]

• Safe demonstration is possible because of the antireflection stickers placed on the slide surface to protect the students’ eyes from laser reflection.

[To students]

• Safe and precise experiment is possible.
• Possible to carry experiment with no worry to damage the surface of the slide with their operation.
