Electromagnetic (EMI) filters and radio frequency interference (RFI) filters purify signals by attenuating the high-frequency RFI (typically 150kHz and up) and passing the low frequency EMI

IC electronic filters are frequency-selective circuits that consist of devices such resistors, capacitors, inductors, transistors, or operational amplifiers coupled with reactive components

Signal amplifiers accept signals from sensors and other devices and amplify them to levels suitable for further processing or digitization by computer elements.

Voltage-to-frequency converters accept a voltage signal and convert its analog level to a signal with a corresponding frequency.

Microscopes are instruments that produce magnified images of small objects

Optical materials consist of glasses, plastics, ceramics and coatings with reflectivity, opacity, color or other properties tailored for mirror, lens, laser or other optics applications.

Active low pass filters pass signals from low frequencies and reject signals from high frequencies

Low pass filters pass signals from low frequencies and reject signals from high frequencies

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

Long pass filters transmit a wide spectral band of long wavelength radiation while blocking short wavelength radiation. Short pass filters transmit a wide spectral band of short wavelength radiation and block long wave radiation

Signal filters block or decrease (attenuate) unwanted frequencies or signal wave characteristics

Liquid filtration elements are used to remove impurities from liquids. They are used in water treatment systems and fluid processing applications.

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

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

Filtration media and elements are designed to remove suspended particles from a process stream. This product area includes bulk filter media, cartridges, housing-only products, and housing and filter assemblies.
