Technical background we can supply for an article
- How substrate material choice (BK7, Boro 3.3, fused silica, quartz, sapphire) is actually decided by wavelength range, thermal load and mechanical envelope.
- Why coated colour filters are specified by transmission curve and blocking band rather than by colour name.
- The cost drivers in a multi-layer dielectric coating: number of layers, chamber runs, masking, yield and inspection time.
- One-stop processing chains — substrate cold fabrication, then coating, then ultrasonic cleaning, then 100% final inspection — and where they break down.
- Dimensional and surface tolerances that genuinely matter for machine vision, LiDAR, medical and stage-lighting optics, and which ones do not.
- Export documentation, packaging and inspection reporting for optical components shipped from China.
