The BP405 narrowband filter is a filter specially designed for the 405nm band, which is widely used in 3D oral scanning and dental imaging applications. It can effectively filter out-of-band light and only allow 405nm light to pass, thereby improving the imaging accuracy and signal-to-noise ratio of the system.

The role of BP405 narrowband filter in 3D oral scanning
- Improve imaging accuracy
3D oral scanners usually use a 405nm near-ultraviolet light source. The BP405 narrowband filter ensures that the scanner receives only 405nm light, reducing interference from other bands, making the imaging system more stable and capturing more accurate tooth structure and oral details. - Reduce ambient light interference
In a dental office or laboratory environment, other light sources (such as indoor lighting and natural light) may interfere with imaging. The BP405 filter can isolate out-of-band light and only transmit light emitted by the 405nm light source, thereby improving imaging contrast and making the scan results clearer. - Enhance 3D reconstruction effect
3D oral scanning requires processing and reconstruction of data from multiple angles. By using the BP405 filter, the scanning system can obtain consistent spectral data, which helps to generate high-quality 3D models, especially in the restoration of details such as tooth edges and surface textures. - Improve system signal-to-noise ratio
The narrowband characteristics of the BP405 filter help the system exclude light with wavelengths other than 405nm, thereby improving the signal-to-noise ratio and making each scanned data point more accurate. This is especially critical in 3D modeling where detail and high resolution are required.
Application areas
- Fluorescence detection: In fluorescence analysis, the BP405 narrowband filter can extract 405nm purple light from the excitation light or fluorescence signal for detecting and analyzing the properties of fluorescent substances.
- Spectral analysis: In spectral analysis instruments, the BP405 narrowband filter can be used to selectively transmit light signals of specific wavelengths for spectral analysis or measurement.
- Biomedical equipment: The BP405 narrowband filter is widely used in biomedical equipment, such as fluorescence microscopes, transcutaneous icterometers, and microplate readers, for observing and analyzing the fluorescence characteristics of biological samples.
