One key characteristic of expanded grating is its ability to achieve a higher diffraction efficiency. This is particularly important in applications where maximizing light extraction and reducing losses are critical, such as in solar panels or LED technology. By optimizing the grating structure, engineers can create devices that harness light more effectively, leading to improved energy conversion and increased brightness.

One of the primary reasons for installing manual rising bollards is to enhance security in specific areas. By restricting vehicle access, these bollards help prevent unauthorized parking, vehicular assaults, and potential terrorist attacks. Their ability to be raised and locked in place ensures that only authorized personnel can enter restricted zones, such as government buildings, parks during special events, or pedestrian-only streets.
