Off-Axis Big Aperture Paraboloid Lenses Combination
Product Details
The traditional manual method is adopted to process the lager diameter paraboloid and hyperboloidlenswithBK7(ZKN4or Zerodur)material, useknife-edgeinstrument for test, with high processing accuracy,and the diameter can be within 900mm.surfaceaccuracy could beless than 1/40 lambda.Through high precision parallel light tube, combined processing method to ensure the image quality of primary and secondary mirror combined system.With knife-edge instrument, the spot size can be controlled within 0.02mm. can also process non-focal beam expansion system, that is, Parallel light comes inand parallel light comes out.Expansioncan be designed according to customerrequirements.
Through the way of sleeve, the combination could beobtained.
