RoHS REACH

An 8K BSI TDI camera with visible or UV sensors and line rates up to 1 MHz for demanding inspection.

The Gemini 8KTDI is a back-illuminated TDI sCMOS camera with an 8208-pixel line of 5 µm pixels and up to 256 stages, offered with a visible-optimized or a UV-enhanced sensor. A 100G or 40G CoaXPress-over-Fiber interface supports 1 MHz in 8/10-bit mode and 500 kHz in 12-bit mode. Temperature-stabilized cooling keeps thermal noise low for biological and industrial inspection.

Key Features

  • Three models: G8KTDI V2 (visible sensor, air and liquid cooling, 100G CoF), G8KTDI-HEX-40G (visible sensor, HEX cooling) and G8KTDI-UV-HEX-40G (UV sensor, HEX cooling)
  • 94.2% typical QE at 460 nm (visible sensor); 65.8% at 266 nm (UV sensor)
  • 1 MHz line rate at 8/10 bit and 500 kHz at 12 bit
  • 8208 Mpixel/s at 1 MHz and 8K, compared with 4590 Mpixel/s for the previous-generation 9K TDI camera at 510 kHz
  • Cooling stabilized to ±0.5°C for low thermal noise and a uniform background
  • PRNU/DSNU correction with hundreds of parameters for scenario-based calibration
  • Up to 256 TDI stages; anti-blooming ≥ 50×; CTE ≥ 0.99993

Typical Applications

  • Wafer inspection
  • Advanced packaging inspection
  • Mask inspection
  • Flat-panel display (FPD) inspection
  • High-throughput gene sequencing
  • Pathology slide scanning
