ViSWIR Lens Series

ViSWIR Fixed Focal Length Lens Series Created for the Latest Visible + SWIR Imaging Sensors

Engineered for the latest SWIR imaging sensor (IMX990/IMX991*).


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.

*Specific floating mechanics to realize Apochromat design.



The ViSWIR HYPER-APO/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 lens 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.

"The introduction of the ViSWIR HYPER-APO and Lite series is the first step." according to Mr. Tim Ogawa, R&D Division Director, CBC Group.  "Computar® will continue to develop a diverse line of high-performance Visible + SWIR sensor lenses in the future."
