VSWIR 400 - 1700 nm
ViSWIR Lite | 2/3″ format ViSWR C-mount lenses
The ViSWIR Lite Series achieves a clear and precise image visible to the SWIR range by applying a multilayer coating to absorb the specific light. The application of a multilayer coating on the metal lens parts makes it possible to minimize the negative lighting effects. The broadband anti-reflection coating is applied on all ViSWIR lens elements, allowing high and stable transmission at a super-wide wavelength range: 400nm to 1,700nm. The ViSWIR series delivers a high-quality image using the latest Visible + SWIR sensors. This high-performance lens is designed for non-visible range imaging allowing diverse applications into multiple markets, including Agriculture, Medical, Remote Sensing, etc.
ViSWIR Hyper-APO | 2/3″ format ViSWR C-mount lenses
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.”
Learn about focus shift
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.
