Optical bandpass filters are designed to transmit a specific waveband. They are composed of many thin layers of dielectric materials, which have differing refractive indices to produce constructive and destructive interference in the transmitted light. Search by Specification | Learn More

RF band pass filters are active or passive circuits that pass signals from a specific frequency band and reject signals from out-of-band frequencies. Surface acoustic wave (SAW) filters, crystal filters, and cavity filters are types of band pass filters. Search by Specification | Learn More

RF filters and microwave filters are devices that pass or reject signals by frequency. Basic types include bandpass filters, band reject filters, low pass filters, and high pass filters. Search by Specification | Learn More

Signal filters block or decrease (attenuate) unwanted frequencies or signal wave characteristics. Search by Specification | Learn More

Active band pass filters are used to attenuate frequencies below and above a range of frequencies (i.e., the bandwidth or passband of the filter). Learn More

Fiber optic filters allow only specific wavelengths to pass into a larger fiber optic system. Learn More

Active filters are electronic filers that use active components such as voltage amplifiers or operational amplifiers. The amplifier shapes and stabilizes the behavior of the filter, and serves as a buffer interface to the driven component. Search by Specification | Learn More

Video cameras take continuous pictures and generate signals for display or recording. They capture images by breaking them down into a series of lines. This search form does not include consumer devices such as camcorders. Search by Specification | Learn More

Camera lenses and video lenses attach to video cameras for use in machine vision, quality monitoring, security, and remote monitoring for industrial and commercial operations. This search form does not cover consumer video camera lenses. Search by Specification | Learn More

Digital filters use digital signal processing (DSP) to perform numerical calculations on sampled values of a signal. Learn More

Passive filters are implemented using only passive components such as resistors, capacitors and inductors. These filters do not produce any amplification of the input signal. Learn More

Color filters include a wide range of filter types that are distinguished by their specific color spectrums and wavelengths, as well as their Schott glass compositions. Search by Specification | Learn More

Charge coupled device (CCD) cameras contain light-sensitive silicon chips that detect electrons excited by incoming light. They also contain micro circuitry that transfers a detected signal along a row of discrete picture elements or pixels, scanning the image very rapidly. CCD cameras use two-dimensional CCD arrays with many thousand of pixels. Search by Specification | Learn More

Complementary metal oxide semiconductor (CMOS) cameras use image sensors that operate at lower voltages than charged coupled devices (CCDs), reducing power consumption for portable applications. Each CMOS active pixel sensor cell has its own buffer amplifier, and can be addressed and read individually. Search by Specification | Learn More
