BP807nm Narrow Bandpass Filter Infrared Laser Measuring Instrument

The NP807nm filter is a precision optical component designed for the 807nm wavelength. Its core function is to selectively transmit specific bands of infrared light while efficiently blocking light of other wavelengths. It is widely used in optical measurement, imaging, and sensing systems. The following sections introduce its technical parameters, functional advantages, and potential application scenarios:

Core Technical Parameters and Performance Characteristics

• Center Wavelength and Bandwidth: Centered at 807nm with a typical bandwidth of 20-30nm (referencing similar narrowband filters like the NP810's 25nm bandwidth standard), ensuring high selectivity for the target wavelength.
• Transmittance and Blocking Capability: Transmittance can exceed 90%, while the optical density (OD value) in non-transmitting regions (e.g., visible light) typically reaches OD4 level, meaning light is suppressed to one ten-thousandth of its original intensity, effectively reducing background light interference.
• Dimensions and Compatibility: Available in various diameter specifications (e.g., 12.7mm, 25.4mm) to adapt to different optical device interfaces, supporting both miniaturized instruments (e.g., portable spectrometers) and large-scale industrial inspection systems.

Functional Positioning and Technical Advantages

• Wavelength Precision: The 807nm wavelength falls within the near-infrared band (700-3000nm), commonly used in laser diodes (LD), fiber optic communication, and biological tissue imaging. The NP807nm filter isolates target signals from environmental stray light through its narrowband characteristics, enhancing the system's signal-to-noise ratio.
