Jollystar releases F-theta scan lens with Focal Length 254mm at wavelength of 532nm for Laser making machines today (Sep 10th,2013). The lens is made up of four glass elements and aluminum lenshouse, similar as the F-theta lens F254-1064 and the F-theta lens F160-1064 . The lenshouse is absolutely robust construction with titanium and aluminum alloy. The glass elements are coated with Multi-layer Coating (Transmission >= 99.8% @ 532nm) to reduce light loss. Its square scan field size is 175mm*175mm, same as the scan field size of F theta lens F254-1064. The F-theta lens can achieve large flat field image with high performance. The diffraction limited performance of the scan lenses results in minimum spot sizes with high uniformity over the whole scan field. Jollystar is making the prototypes of the lenses. And the lens can be sent to your store from on the Oct 15th.
