Computar ViSWIR lens series – Hyper APO

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.

Hyper APO

No focus shift 400-1700 nm

Iris range

F1.4 - F/16

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.
