K9 Glass LP910nm Longpass Infrared Filter

Application Fields of NP910nm Optical Filter

Based on its wavelength characteristics and optical performance, the NP910nm bandpass filter is primarily used in the following scenarios:

• Fluorescence Analysis and Detection Equipment: Such as PCR fluorescence analyzers, where the 910nm wavelength matches the emission spectrum of specific fluorescent probes. The filter screens target fluorescence signals to improve detection accuracy.
• Infrared Optical Systems: Including infrared sensors and surveillance cameras, where the filter eliminates interference bands from ambient light, enhancing the clarity of infrared imaging or detection.
• Optical Detection Instruments: Used in devices like barcode scanners and laser rangefinders to extract laser signals around 910nm, reducing the impact of background light noise on measurement results.

Key Points for Selection and Customization of NP910nm Optical Filter

• Parameter Matching: It is necessary to confirm whether the center wavelength and full width at half maximum (FWHM) align with the parameters of the specific equipment, such as the light source wavelength and detector sensitivity. For example, laser rangefinders require strict matching with the 910nm wavelength of the laser source to avoid signal attenuation due to center wavelength deviation.
• Cutoff Depth Requirements: In high ambient light environments (e.g., outdoor detection), filters with higher cutoff depths (e.g., OD5-OD6) are needed, while OD3-OD4 may suffice in laboratory settings.
• Size and Material: The filter size must match the optical aperture of the system, and the material affects physical properties such as high-temperature resistance and corrosion resistance. Customization is available based on the usage environment.
