Optical Filters

Longpass Filters, also known as Longpass Edge Filters, are designed to transmit wavelengths greater than the cut-on wavelength of the filter. Read more...

Bandpass Filters are used to selectively transmit a portion of the spectrum while rejecting all other wavelengths. Yutai Optics offers a wide variety of Bandpass Filters in a range of bandwidth options for ultraviolet (UV), visible (VIS), or infrared (IR) applications. Read more...

Different IR filters from Yutai Optics: a. optical glass with infrared coating. b. some color glass play an IR filter itself. c. Si, Ge, ZnSe, Sapphire, CaF2, quartz glass with infrared coating. Read more...

Avantier manufactures a wide range of custom optical filters, including hard coated dichroic filters and machine vision filters with excellent performance, ensuring optimal image contrast and accuracy by selectively transmitting specific wavelengths while blocking unwanted light. They are thin, offer high transmission, and are ideal for precision-demanding applications. Customization ava... Read more...

In high-end applications such as optical inspection, fluorescence analysis, and laser measurements, ambient stray light or band-specific interferences often result in signal distortions that affect data accuracy. Our Notch Filters provide efficient band suppression solutions with superior optical performance, ensuring signal purity and system reliability. Read more...

A longpass infrared filter is an optical element that allows infrared light with wavelengths greater than a specific cut-off wavelength to pass through while blocking shorter wavelengths (such as visible or near-infrared light). Read more...

In infrared optical systems, filters play a critical role in precisely controlling the passage of light at specific wavelengths to optimize imaging quality or signal detection. Read more...

An infrared cut-off filter (IR Cut Filter) is an optical element that is mainly used to block infrared light (wavelength usually greater than 700nm) and allow visible light (about 400-700nm) to pass through. It is widely used in modern imaging systems, especially in digital cameras, smartphone cameras, security surveillance and other areas of critical importance. Read more...

An absorptive neutral density filter (ND Filter) is an optical element that uniformly reduces the intensity of light by absorbing light of a specific wavelength. It does not significantly change the color of light (i.e., remains “neutral”) and is widely used in photography, laser systems, spectral analysis, and other applications. Read more...

UV bandpass filters from Yutai Optics are optical elements for the ultraviolet wavelength range (typically 100-400nm) that allow only light in a specific ultraviolet wavelength range to pass through while blocking other wavelengths (such as visible and infrared light). Read more...
