Measurement & Safety
COL-200 to COL-600 configurations
Full-Spectrum Optical Parameter Testing
A modular optical-test platform combining a collimator, multi-spectral target generator, precision rotation stage and image analyser. Configure UV, visible, SWIR, MWIR or LWIR paths for MTF and imaging-performance measurements.
How the measurement works
Present controlled targets to the optical system under test, position the sample and analyse its image. Workflows cover on-axis/off-axis and through-focus MTF, effective focal length, distortion, relative illumination, field curvature, astigmatism, depth of field, lateral chromatic aberration and encircled energy.
Features
- UV through LWIR configurations
- Interchangeable collimator options
- Custom rotation-stage range, encoder resolution and control
- Automated through-focus and imaging-analysis workflows
Applications
- Optical-system development and verification
- Imaging components for communications and sensing
- Biomedical, materials and display research
