Products/Services for narrow band filter
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 about Optical Bandpass Filters
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 about RF Filters and Microwave Filters
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 about RF Band Pass Filters
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 about Active Band Pass Filters
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 about Active Filters
Active band reject filters are tuned circuits that prevent the passage of signals within a specified band of frequencies. These devices are also known as bandstop or notch filters. Learn More about Active Band Reject Filters
...regions on an assembly. Some UV systems can feed multiple wands or light pipes. Most UV curing systems produce ultraviolet radiation falling into one to three UV bands: UVA, UVB and UVC. UVA is the near or long wave UV band (~315 - 400 nm). Also... Search by Specification | Learn More about UV Curing Equipment
RF band reject filters are tuned circuits that prevent the passage of signals within a specified band of frequencies. These devices are also known as bandstop or notch filters. Search by Specification | Learn More about RF Band Reject Filters
Signal filters block or decrease (attenuate) unwanted frequencies or signal wave characteristics. Search by Specification | Learn More about Signal Filters
Digital filters use digital signal processing (DSP) to perform numerical calculations on sampled values of a signal. Learn More about Digital 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. Learn More about Passive Filters
RF high pass filters pass signals from high frequencies and reject signals from low frequencies. Search by Specification | Learn More about RF High Pass Filters
Industrial air filters reduce the number of particles in the air that passes through them. Search by Specification | Learn More about Industrial Air Filters
RF low pass filters pass signals from low frequencies and reject signals from high frequencies. Search by Specification | Learn More about RF Low Pass Filters
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. Search by Specification | Learn More about Long Pass Filters and Short Pass Filters

Optical bandpass Filter
Eliminating all but a narrow band of light (+/- 40nm) centered onthe specified wavelength, bandpass filters are used to enhancecolors, or to stop unwanted ambient light from reaching the cam-era. (read more)
Bandpass Filters
Band-pass filters are usually divided in two groups: 1. Broadband pass filters, and 2. Narrowband pass filters. Although there are no bandwidth values that define narrow or broad filters in UV or visible or in IR, it is common to consider filters that have bandwidth 2% or less of the central or peak wavelength as narrowband.
