Long Pass Optical Filter 700nm Pentru Securitate Și Supraveghere

A long pass optical filter 700nm is a type of optical filter that transmits light above a certain wavelength, while blocking or attenuating light below that wavelength. In the case of a long-pass filter with a cutoff wavelength of 700nm, it would allow light with wavelengths greater than or equal to 700nm to pass through, while blocking or reducing the intensity of light with wavelengths below 700nm.

Cu a high level of blocking achieved at shorter wavelengths and a steep transition from transmission to blocking, LP700nm filter provides exceptional performance and reliability, strong durability and high signal-to-noise ratio. Whether used in fluorescence microscopy, photography, or other optical applications, our long-pass filter deliver superior results and enables precise control over the light transmitted through your system.

Cum face long pass optic filtru 700nm aplică in securitate și supraveghere?

Long-pass optical filters with a cutoff wavelength of 700nm can be used in security and surveillance applications to improve image quality and reduce false alarms. In low-light or no-light environments, security cameras often rely on infrared (IR) illumination to capture images. However, this IR illumination can sometimes be reflected or scattered by various surfaces, resulting in an overexposed image or false alarms due to motion detection .

A LP700nm filter can be used to block visible light while allowing IR light to pass through. This helps to reduce the effects of visible light reflection or scattering, and enhances the detection of IR radiation emitted by objects or people in the scene. This results in improved image quality and accuracy of motion detection, which is critical for effective security and surveillance systems.

În plus, the use of long-pass filters in security and surveillance applications can also enhance privacy by limiting the visibility of certain details or objects, such as license plates or faces. By selectively blocking visible light and allowing IR light to pass through 2c long-pass filters can provide a level of anonymity and privacy protection for individuals and vehicles in the scene.
