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

STY--- STY series laser f-theta lenses
  xxxx-- laser wavelength, 1064 means 1064nm, 10.6 means 10.6um.
  yyy---- mark field (scan field), yyy x yyy mm
  zzz---- effective focal length in mm
  dd------ entrance pupil (allowed maximum input laser beam diameter) in mm (option)
A------ others

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.
