Optical 650nm Visible Light 940nm Dual Filter Glass

  Custom Optical 650nm Visible Light 940nm Dual Filter Glass For Camera Lens   A dual-band pass filter with wavelengths of 650nm and 940nm is a specialized optical component designed to selectively transmit light at two specific wavelengths while blocking other wavelengths. This type of filter is commonly used in various applications where it's necessary to isolate and work with these particular wavelengths, such as in biomedical imaging, remote sensing, or certain types of optical communication systems. Specification:   Surface Quality 60/40 CWL 650NM+940NM Transmistance above 90% FWHM 10nm to 85nm upon request Mounted Thread Mounted as Require Samples Available Key Features: - Wavelengths: The filter allows the passage of light at 650nm (in the red part of the visible spectrum) and 940nm (in the near-infrared region).- Transmission Bands: The transmission bands around these wavelengths are typically narrow, ensuring that only a small range of wavelengths around 6…
