Bringing the ViSWIR Gap: High-Resolution Multi-Spectral Imaging via API-Driven Focus
In the world of VISWIR (Visible + Short-Wave Infrared) imaging, the hardware cost of “perfect” optics often stalls projects in the prototyping phase. CBC’s ViSWIR HyperApo series eliminated focus shift through complex glass elements, but the price point reflected that engineering.
The introduction of the LensConnect Vario VISWIR series (5.5-16mm and 12-35mm) offers a new path for developers: Software-Compensated Multi-spectral Imaging.
Solving the Focus Shift Headache
In multi-spectral applications—such as fruit sorting, silicon wafer inspection, or moisture detection—switching from visible light to 1450nm causes a significant focus shift. For a standard lens, this requires manual calibration or expensive apochromatic correction.
With the LensConnect Vario models, the focus is controlled via I2C or USB. Developers can now:
Perform high-speed refocusing when switching illumination sources.
Store look-up tables (LUTs) within their software to instantly compensate for wavelength-specific focus shifts.
Works best with IMX 992 and 993 Sensor generation.
Developer ROI: Significant Less CAPEX, Zero Manual Intervention
By opting for the Vario series over the HyperApo, system integrators realize an immediate reduction in lens costs. For a deployment of 10+ inspection lines, this represents a massive boost to the project’s ROI. The “Ease of Use” for the developer is found in the integration; the LensConnect architecture eliminates external motor drivers, allowing for a “Plug-and-Play” multi-spectral setup that can be tuned remotely.
Key Technical Specs:
Focal Ranges: 5.5mm – 16mm | 12mm – 35mm
Spectrum: Optimized for 400 nm to 1700 nm
Interface: Native USB / I2C (and RS-type coming 2026)
Precision: High-repeatability focus steps for consistent software-based compensation.
Conclusion
If your application requires simultaneous focus across all bands, the HyperApo remains your choice. However, if your system uses sequential lighting or can afford a millisecond refocusing trigger, the LensConnect Vario VISWIR is the most cost-effective, high-resolution solution on the market today.
