The UV + IR Cut Filter is designed for use with industrial cameras and machine vision lenses to transmit only the visible spectrum (approximately 398–698 nm) while blocking unwanted ultraviolet (UV) and infrared (IR) light. It mounts directly to the front of a standard machine vision lens using the threaded filter mount, providing an effective way to maintain stable and consistent image quality under varying illumination conditions. UV + IR cut filter Function and Spectral Performance At the useful wavelength range of 398–698 nm, the UV + IR Cut Filter provides a transmission rate above 80%. Light with wavelengths below 398 nm (UV region) and above 698 nm (IR region) is strongly blocked. By removing these non-visible components, the filter prevents unwanted spectral energy from reaching the camera sensor, which can cause color distortion, reduced contrast, and loss of sharpness. The result is a clean, color-accurate image, particularly in applications where broadband or ambient illumination includes UV or IR light that could interfere with the visible spectrum. Typical Applications for UV + IR cut filter · Color imaging in visible-light machine vision systems · Inspection under mixed or uncontrolled lighting conditions · Reducing chromatic aberration in broadband illumination setups · Enhancing color fidelity in CCD and CMOS cameras · Improving precision in color-based measurement or sorting tasks UV + IR cut filter Key Features and Benefits · Transmits visible light (398–698 nm) with >80% efficiency · Blocks unwanted UV (698 nm) radiation · Enhances image contrast and overall sharpness · Improves color accuracy in RGB or Bayer-pattern cameras · Compatible with standard threaded machine vision lenses Integration and Mounting for UV + IR cut filter The UV + IR Cut Filter can be mounted directly onto most machine vision lenses using a standard filter thread. If the lens does not include a front filter thread, the filter can also be installed inside the C-mount interface, positioned between the camera and lens. This mounting method keeps the filter aligned in the optical path, maintaining consistent imaging performance without requiring hardware modification. Available in a range of standard thread sizes, these filters are compatible with both compact and large-scale optical setups.
