產品特色Features

ULO Optics' multi-element f-Theta lenses are designed for superior performance for working distances between 75 and 300 mm and field sizes up to 210 x 210 mm, for high power laser applications like marking, welding and structuring. The ZnSe lenses are highly transmissive and are mounted in an aluminum housing for easy handling. A protective window can be included and is recommended for short working distances. Our lenses are available with different coatings as needed.

The ZSD-15 series doublets contain ZnSe elements made from the same laser grade ZnSe and fully coated with low absorption anti-reflection coatings. They are capable of handling high powers while focusing down to smaller spots.

● focal lengths 75 and 100mm respectively, where higher performance than the

doublets is required
● the 75mm focal length lens is also nearly telecentric (see below) with the focused beam

less than 5° to the normal
● diffraction limited performance over the entire image plane
● can be fitted with a protective window

Part Number	Field Size	Focal Length	Spot Diameter (s.d.)*

ZST-15-100	70 mm	100 mm	113 (1) micron

s.d.* = Standard deviation

Spot diameter is determined from optical computation and are not measured values from marking or engraving. The width of an engraved line is affected by laser power, material, scan speed, etc and is normally less than the values listed here.
