Various F-Theta Lenses

  • Update:Jul 27, 2021
  • View:

F-theta lenses are used in laser scanners (laser markers) and the laser wavelengths may be 355nm 266nm and other wavelengths. We can provide full range of f-theta lenses according to your applications.

We are promoting laser lamps, galvos, marking heads, green laser pointers etc till the stock is sold out. Pleasee click here.

 

Description of STY series f-theta Lenses: STY-xxxx-yyy-zzz-dd-A

Remark: (1) The f-theta lens consists of 3 lenses and one protective window/glass. The coating is a di-electric layer. The transmission is >99% at 1064nm. Two sides of the protective glass are AR-coated at 1064nm.
(2) In the following tables, the abbreviations are as follows: FL means effective focal length; EP means max. input beam diameter; SAR means scan area, AS means aperture stop; WD means working distance; OD means max. outside diameter; MT means mount thread, fs means fused silica, SA means max. full diagonal scan angle; L2 (a1) means recommended mirror separation; a2 means 2nd mirror to flange, L1 means the distance 2nd mirror and scan lens, SL means scan length, Length means the total length of the scan lens, WC means water cooled.
