Computar ViSWIR: Hyper-Spectral and Multi-Spectral Lens Series Created for the Latest Visible and SWIR Imaging Sensors
Computar Optics GroupRequest Info
The ViSWIR lens series captures images across a broad spectrum, from visible light to short-wave infrared (SWIR), making them innovative for their wide spectral range and high-resolution imaging capabilities. Their compact form factor is engineered for the latest SWIR imaging sensors (IMX990/IMX991*) and achieve a fully-corrected focus shift in visible and SWIR range (400 nm - 1700 nm). Using ultra-low and low partial dispersion glass paired with superior design technology minimizes the focus shift within a few micron mm at a super wide range of wavelengths. With this, spectral imaging is achievable with a single-sensor camera by simply syncing the lighting.
With the ViSWIR HYPER-APO lenses, adjusting focus for different wavelengths is unnecessary. 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.
ViSWIR's cross-spectral capabilities allow for high-quality imaging with a single lens in visible and SWIR spectrums, simplifying systems that previously required multiple imaging devices — enhancing detection and analysis capabilities beyond what is possible with standard cameras.
The ViSWIR lenses serve various photonics applications and markets, including industrial inspection, security and surveillance, agriculture, scientific research, and medical imaging. They facilitate quality control in industrial settings by providing detailed imaging across a wide spectral range. For security applications, they offer enhanced imaging in low-light conditions and through obscurants like fog or smoke. In agriculture, SWIR imaging can help identify plant stress early, while in scientific research and medical imaging, the lenses enable detailed analysis that is impossible with traditional imaging systems. This versatility and innovation make the ViSWIR series a noteworthy development in photonics technology.
