What type of surface do anodized instruments have that helps to disperse laser light?

Anodized instruments possess a roughened surface that plays a crucial role in dispersing laser light. The roughened texture increases the surface area, allowing for more interaction between the laser light and the instrument. This interaction helps to scatter the light rather than allowing it to reflect directly off a flat or smooth surface.

By dispersing the laser light, anodized instruments can facilitate better absorption and distribution of energy when used in various laser applications, enhancing their effectiveness. In contrast, smooth or polished surfaces tend to reflect light more directly, which might not be ideal for laser interactions that require significant light distribution. This makes the roughened surface particularly advantageous in laser treatments where even energy delivery is critical.
