LensCal XR Optical Calibration System

Sub-micron focal alignment for multi-sensor arrays

The LensCal XR system is designed for laboratories and production lines requiring sub-micron accuracy in focal distance and refractive index measurement. It integrates a motorized test bench with a laser interferometer and real-time software for automated calibration of camera lenses and sensor stacks. The system supports lenses from 5mm to 200mm diameter and provides a calibration report with traceable uncertainty values. Ideal for sorting machine manufacturers and robotic vision integrators who need consistent optical performance across multiple units.

RoboVision Positioning Toolkit

Coordinate mapping and sensor placement suite

The RoboVision Positioning Toolkit is a software and hardware bundle for designing optimal sensor layouts in robotic workcells. It includes a 3D simulation environment, a calibration target set, and a coordinate transformation library. Engineers can simulate light paths, test occlusion scenarios, and generate placement coordinates for cameras and LIDAR sensors. The toolkit outputs machine-readable configuration files for direct integration with PLCs and robot controllers. It reduces sensor alignment time by up to 60% in prototype and production setups.

MineralScan Spectral Calibration Reference

Certified optical standards for sorting machine sensors

The MineralScan Spectral Calibration Reference is a set of certified optical standards for calibrating hyperspectral and multispectral sensors used in mineral sorting. Each reference tile is manufactured with precisely controlled reflectance values across the visible and near-infrared spectrum. The set includes a calibration protocol and software for automated sensor response correction. It ensures that sorting machines maintain consistent classification accuracy across different lighting conditions and sensor aging. The reference is traceable to national metrology institutes and comes with a five-year stability guarantee.

Frequently Asked Questions

Clear answers about optical calibration, sensor layout, and robotic vision positioning.

What types of lenses and sensors do you calibrate?

We calibrate camera lenses from 5 mm to 200 mm diameter, including multi-sensor arrays used in industrial robotics, mineral scanners, and sorting machines. Our process covers focal distance, refractive index, and spectral response for visible and near-infrared ranges.

How does your sensor placement service work?

Our RoboVision Positioning Toolkit combines 3D simulation, occlusion testing, and coordinate mapping to determine optimal camera and LIDAR positions in a robotic workcell. We deliver machine-readable configuration files for direct PLC and robot controller integration.

Do you provide calibration reports with traceable values?

Yes. Every calibration includes a report with traceable uncertainty values referenced to national metrology institutes. Our MineralScan Spectral Calibration Reference tiles come with a five-year stability guarantee and automated sensor response correction software.

Is your service separate from security or surveillance systems?

Completely. We focus exclusively on precision metrology, optical alignment, and sensor layout for industrial robotics and mineral sorting. We do not work with alarms, home surveillance, or security camera systems.

What is the typical turnaround for a calibration project?

Turnaround depends on lens volume and complexity. A single-lens calibration with report can be completed within two business days. Multi-sensor array projects or custom sensor layout designs typically take one to two weeks, including simulation and documentation.

Can you integrate calibration data into our existing production line?

Yes. We output calibration files in standard formats compatible with most PLCs and robot controllers. Our team can also work with your engineers to adapt the data format or coordinate system to match your existing workflow.

Scope & Definitions

This section clarifies the technical boundaries, measurement standards, and service conditions that apply to all calibration, positioning, and sensor layout work performed by Ozcctv.

Calibration Scope

  • • Focal distance measurement uncertainty: ±0.5 µm per meter of working distance.
  • • Refractive index testing performed at 23 °C ±1 °C ambient temperature.
  • • Sensor alignment tolerances follow ISO 10360-2 coordinate metrology standards.
  • • Calibration reports include traceability to SI units via NMI-certified references.

Positioning & Layout

  • • Sensor placement coordinates are generated using a 6-DOF kinematic model of the robotic workcell.
  • • Occlusion analysis accounts for arm reach, tooling envelope, and fixed obstructions.
  • • Layout designs assume a maximum ambient light variation of ±5 lux during operation.
  • • Final configuration files are validated against the robot controller’s native coordinate system.

Service Exclusions

  • • No work involving security cameras, alarm systems, or home surveillance equipment.
  • • On-site calibration requires a clean, vibration-controlled environment (ISO 8 or better).
  • • Customer-provided lenses must have undamaged optical coatings and no visible scratches.
  • • Software integration support is limited to the interfaces specified in the project scope.

Measurement Conditions

  • • All optical tests are conducted in a darkroom with controlled humidity (40–60% RH).
  • • Reference standards are recalibrated every 12 months or after 500 measurement cycles.
  • • Reported uncertainties include combined contributions from the instrument, operator, and environment.
  • • Data from each calibration is logged with a unique serial number and timestamp.

These definitions apply to all proposals, contracts, and deliverables unless superseded by a written agreement signed by both parties. Ozcctv reserves the right to update these terms with 30 days’ notice.
