Working Principle of UV-IR Cutoff Filter
The UV-IR cut-off filter works based on multi-layer optical thin film coating technology, which can block short-wave ultraviolet light and long-wave infrared light to prevent these invisible lights from interfering with imaging. Typically, these filters cut off ultraviolet light in the range of 300-400nm and infrared light in the range of 700-1100nm, thus allowing only visible light of 400-700nm to pass through.
Product Advantages
Improve imaging quality: effectively block unnecessary ultraviolet and infrared light, improve the image clarity and color accuracy of the device.
Reduce thermal interference: ultraviolet and infrared light will produce thermal effects, and filter isolation can reduce the impact of heat on imaging equipment or samples.
Multi-scenario applicability: Whether it is digital photography, industrial inspection or medical imaging, UV-IR cutoff filters can provide the system with more accurate spectral selectivity and are widely used in a variety of scenarios. High transmittance and high stability: The filter has high transmittance and stable performance in the visible light range, suitable for long-term use.
Application fields
Digital imaging:
In digital cameras and video equipment, ultraviolet and infrared light may cause blurred images or color distortion. Using UV-IR cutoff filters can effectively improve the imaging effect, making the colors of photos more realistic and the pictures clearer.
Security monitoring:
In security cameras, the effect of ultraviolet infrared cutoff filters can avoid the influence of infrared light on daytime imaging and improve the fineness and realism of monitoring images.
Microscope observation:
In microscopic imaging equipment, ultraviolet and infrared light may affect the observation effect of samples. Cutoff filters can effectively isolate these invisible lights to ensure high-quality microscopic imaging, especially in the observation of living cells, reducing the impact of thermal effects on samples.
Industrial detection:
The interference of ultraviolet and infrared light may affect the accuracy of industrial vision systems. Ultraviolet infrared cutoff filters can ensure the quality of visible light in mechanical vision detection, avoid false detection, and improve detection accuracy.
Medical imaging:
In medical imaging equipment such as endoscopes and X-rays, cutoff filters help improve image clarity, reduce the thermal impact of infrared radiation on patients, and ensure accurate imaging.
