BigEye M42 and M42 to C or F Mount USB3.0 CMOS Microscope Camera

BigEye M42 to C or F Mount USB3.0 CMOS Microscope Camera is a high-speed, high-sensitivity digital imaging solution for biological, metallurgical, and electronics inspection microscopes. The series supports 4.2M and 10.3M sensor options with global shutter, monochrome or color output, and flexible mounting via M42, C, or F mount adapters. Designed for integration with USB3.0 systems, it enables real-time imaging and data capture with exposure times from 0.01ms to 60s.

  • Supports 4.2M and 10.3M sensor options with high quantum efficiency and low dark signal
  • M42, C, or F mount adaptability for direct integration with existing microscope bodies
  • High frame rates up to 86 FPS at 1360×720 resolution for dynamic inspection tasks
  • Flexible exposure control from 0.01ms to 60s for low-light and high-speed applications
  • Multiple output formats including RAW12, 12bit, and 16bit HDR for advanced image processing

Use guide

  • Select sensor size and resolution (4.2M vs 10.3M) based on required field of view and detail level
  • Choose monochrome or color output depending on application (e.g., color for tissue, monochrome for metal)
  • Match mounting adapter (M42, C, or F) to the microscope's lens thread
  • Confirm interface (USB3.0 or MIPI) with host system (PC or embedded processor)
  • Set exposure time and binning based on lighting conditions and motion speed
