Ensuring Excellence: Quality Control for Rays Optics

Splitting Ratio Accuracy Verification

We utilize calibrated spectrometers and laser sources to measure the exact transmission/reflection ratio (e.g., 50:50, 70:30) at the specified wavelength, ensuring deviation is within ±2% of the target value for optimal performance.

Surface Flatness & Wavefront Distortion Test

Each optical surface is inspected using a laser interferometer to quantify flatness, typically guaranteeing λ/10 or better, thereby minimizing wavefront distortion and preserving beam quality.

Polarization-Dependent Loss (PDL) Assessment

For non-polarizing cube beamsplitters, we measure the maximum variation in splitting ratio with incident polarization, maintaining PDL below 0.5% to ensure consistent performance regardless of input polarization state.

Polarization Extinction Ratio (PER) Certification

For Polarizing Beamsplitter Cubes (PBCs), we certify the extinction ratio for both transmitted (typically >500:1) and reflected beams, guaranteeing high-purity S and P polarization separation.

Spectral Performance & Coating Uniformity Check

We validate the coating's spectral response across the specified wavelength range (e.g., 400-700nm), ensuring uniformity across the clear aperture to prevent intensity gradients.

Beam Deviation & Angular Accuracy Measurement

For cube beamsplitters, we precisely measure the deviation angle between transmitted and reflected beams, ensuring they maintain exact 90-degree separation as designed.
