Fully corrected focus shift in visible and SWIR range (400nm-1,700nm): “By using ultra-low dispersion glass and low partial dispersion glass paired with superior design technology developed from Computar’s extensive optics experience, the focus shift is minimized within a few micron mm at a super wide range of wavelengths.” according to Mr. Katsuya Hirano, Chief Optical Designer, CBC Group. “With this, spectral imaging is achievable with a single sensor camera by simply syncing the lighting.”
With ViSWIR HYPER-APO, it is unnecessary to adjust focus for different wavelengths or to keep the resolution high from short to long working distances. By adopting an APO floating design*, the focus shift is reduced at any wavelength and any working distance. This function makes the series ideal for multiple applications, including machine vision, UAV, and remote sensing.
