Product Description

The 650nm optical filter features strong infrared suppression and is compatible with RGB color image sensors .

 

I. Core Basic Introduction:

 

1. Definition: Based on optical coating technology, a multi-layer dielectric film is formed on an optical substrate to achieve a steep cutoff at 650nm wavelength, separating the target wavelength band from the interference wavelength band, and eliminating the "narrow passband" characteristic of narrowband filters;

 

2. Substrate and Process: The mainstream substrates are optical glass (cost-effective), quartz (high stability), and sapphire (wear-resistant); vacuum magnetron sputtering coating is used, resulting in a dense film layer and stable performance;

 

3. Core Applications:

  • Short-wavelength 650nm cutoff: Suppresses near-infrared stray light, adapting to visible light imaging (such as outdoor QR code scanning, avoiding interference from 700nm+ infrared light sensors);
  • Long-wavelength 650nm cutoff: Retains near-infrared/red light, used for NIR imaging, laser ranging, and bio-detection (such as in QR code scanning scenarios with 650nm+ laser light sources);
  • Application scenarios: vehicle-mounted imaging equipment, digital imaging products, security cameras, access control and face recognition devices, code-scanning vision and barcode reading cameras, etc.

4. Size Adaptation: Standard sizes include 4mm×4mm, 8mm×8mm, etc., and can be customized to fit the optical path and structural space of camera modules.

 

II. Customized Services (Meeting Customer Needs for Different Wavelengths and Specifications):

 

1. Wavelength Customization:

  • In addition to 650nm, short-pass/long-pass filters with any cutoff wavelength, such as 850nm and 940nm, can be customized.
  • Composite cutoff solutions" can be customized (e.g., simultaneously cutting off 650nm+ and 400nm-, retaining the intermediate visible light region).

2. Specification Customization:

       · Size and Shape: Round, square, minimum size 1mm×1mm, thickness can be adjusted as needed (e.g., 0.21mm, 0.5mm, 1mm);

  • Base Material: Optical glass (cost priority), quartz (high stability), sapphire (wear-resistant);
  • Mounting Adaptation: Added adhesive steps, anti-reflective coating, suitable for snap-on and adhesive-bonded camera module installation.

3. Customized Special Functions: 

  • UV-cut composite coating, anti-glare treatment, waterproof and anti-fog coating;
  • film reinforcement solutions adapted to extreme environments (such as high temperature, high humidity, strong vibration).
