OBJECTIVE LENS

The optical system used to convey an image from Infinity-corrected optical system, the objective lens to the CCD Tube Lens. The improved illumination uniformity and Contrast for the overall image of the implementation was a clear, sharp image of the microscope system combined with the Infinity Objective Lens Tube Lens Compact and configured using Koehler illumination system are coaxial.

Correcting the chromatic aberration as the most critical parts of the microscope to magnify the objects was at the wavelength of blue and red are Achromatic Objective Lens. Objective Lens is Apochromatic Objective Lens corrects the chromatic aberration of the three wavelengths to have a higher NA of the white light source in the System Fits. 

High-Power NIR/ UV Objectives Lens

NIR/UV fused silica lenses
  • Infinity corrected, ideal for laser applications
  • Excellent wavefront quality
  • High damage threshold
