Overview

F-theta scan lens for UV lasers. Price varies with scan field size. High purity silica glass is required to prevent the UV laser from marking the optics. These elements are more expensive than standard glass elements resulting in a higher price tag. Cheap UV optics use lower purity silica or low quality coatings which will degrade over time with continued use. As of writing WTS offers the following field sizes:70x70 | 110x110 | 150x150 | 175x175 | 210x210 | 300x300
