UV Fused Silica Double Convex Lens

  1. Double convex lens have positive focal length.
  2. DCX lens can converge light to form real image.
  3. Suitable for finite conjugate imaging application.
  4. UV fused silica offers high transmission in UV region.
  5. UV fused silica exhibits low laser-induced fluorescence.
  6. Fused silica has high bulk damage threshold and lower thermal coefficient compared to N-BK7.

Application Notes

  1. BCX for Imaging :                                                                                                                                                                            BCX Lens is used for finite conjugate imaging (ratio of object distance : image distance = 0.2 to 5), object and image being on opposite side of Lens. 
  2. BCX at 2F-2F :                                                                                                                                                                                BCX Lens exhibit minimal Spherical Aberrations at 1:1 conjugate ratio also known as 2F-2F imaging, additionally at this ratio coma and distortion is cancelled.
  3. BCX uses :                                                                                                                                                                                      BCX Lenses are used for imaging in telescopes, monocular, projectors, image relays.
