Product Summary

Filter by MidOpt, Mounted Band Pass Filter, Cyan: An absorptive band pass filter for cyan light, with a shorter bound of 470nm and a longer bound of 560nm.

The BN660-25.4 Dark Red Bandpass Filter by MidOpt is tailored to transmit light in the 640 nm to 680 nm wavelength range, ensuring that only the desired dark red light is captured while blocking out all other environmental light. This absorptive bandpass filter is ideal for use with LED or laser diode applications, where control over the visible light spectrum is critical to achieving high-quality imaging results. The filter features a standard C-mount thread, making it compatible with C or CS mount cameras for quick and easy integration. Constructed with durable materials, the BN660-25.4 provides long-lasting performance, even in demanding industrial or research environments. This makes it particularly suitable for machine vision, industrial inspection, and scientific imaging tasks.

Key Features:

  • Dark Red Light Transmission: Filters light between 640 nm and 680 nm for precise imaging results.
  • Improved Signal Quality: Absorptive design enhances image clarity by blocking unwanted light.
  • Seamless Integration: Fits C-mount and CS-mount cameras for easy installation.
  • Durable Design: Built to withstand rigorous use in industrial and scientific settings.
  • Other Sizes Available: Various sizes available to suit different imaging setups.

Technical Specifications:

  • Wavelength Range: 640 nm to 680 nm
  • Mount Type: C-mount and CS-mount
  • Filter Type: Absorptive Bandpass
