Brand Name:
Chippack
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:
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:
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);
3. Customized Special Functions:
