100 mm diameter), narrow bandpass filters (NBPF) are required in many fields. 1. Standard Narrow Bandpass Filters in stock, subject to prior sales (Wavelength range UV, VIS, NIR & IR). This Q Factor is a measure of how “Selective” or “Un-selective” the band pass filter is towards a given spread of frequencies. The filters & components have to be pulled from stock, cleaned, re-measured and checked by QC, packed and shipped. The width of such a filter is expressed in the wavelength range it lets through and can be anything from much less than an Ångström to a few hundred nanometers. Optical band-pass filters are common in photography and theatre lighting work. This band pass filter is called as Narrow Band Pass Filter. An example of an analogue electronic band-pass filter is an RLC circuit (a resistor–inductor–capacitor circuit). These are respectively referred to as narrow-band and wide-band filters. Band-pass filters only transmit a certain wavelength band, and block others. The resonance circuit is used to implement a narrow band filter.

Narrow-band Filters. bandpass uses a minimum-order filter with a stopband attenuation of 60 dB and compensates for the delay introduced by the filter. Our filter designs are particularly unique because we can produce passbands of <1 nm and still achieve, thanks to a special monitoring process, transmissions of 90%.
