For example, Linear Variable Filters (LVF) for use in laboratory analysis systems. Thanks to a special coating technology, these filters have a precisely defined spectral response.

A Linear Variable Bandpass Filter is a wedged filter, whose spectral properties vary linearly along the length of the filter. It is possible to adjust the center wavelength by sliding the filter with ...

A H13 filter can capture 99.95% of particles as small as 0.2 microns, and a H14 filter can capture 99.995% of those particles. A filter must meet specific standards to be called a HEPA filter ...

Fundamentals of analog filter design and linear circuits are covered in a book and kit of parts that are available on EIM Tech's site after a successful ~$108,000 Kickstarter campaign.

The filter has an impedance of 75 ohms and is economical, both in the number of circuit elements employed and in the space needed for mounting, since it measures only 6 in. by 2 11/16 in. by 2 13/ ...
