What is a significant advantage of absorption filters?

Absorption filters are designed to selectively absorb specific wavelengths of light while allowing others to pass through. One significant advantage of absorption filters is their ability to effectively provide UV protection. This is crucial in laser safety applications, as exposure to UV radiation, which can lead to skin burns or ocular damage, needs to be minimized.

While impact resistance is an important feature for certain types of filters, it is not exclusive to absorption filters and does not represent the primary advantage of this type. Moreover, absorption filters can be made from specific materials, typically glass or plastics that have been treated to absorb certain wavelengths, which limits the choices of materials rather than allowing them to be made from any material. The weight of the filter can vary depending on the material and thickness but is not a defining advantage. Therefore, the ability of absorption filters to provide UV protection is a critical benefit in settings where exposure to such radiation is a concern, making it the correct answer.
