Hørsholm, Denmark, April 21st 2016 – Delta Optical Thin Film A/S announces the launch of several Linear Variable Bandpass Filters that are specifically designed for Hyperspectral Imaging.

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.

Edinburgh Biosciences and Delta Optical Thin Film A/S jointly announce a laser attenuator based on linear variable filter technology Date Announced: 12 Jun 2015 Edinburgh/Hørsholm June 15, 2015 – ...

Using patterned graphene/insulator stacks, we demonstrate widely tunable far-infrared notch filters with 8.2 dB rejection ratios and terahertz linear polarizers with 9.5 dB extinction ratios.

Comparison of MDM and transmissive UV filters with a 2- bounce reflective filter. Top: linear scale, Bottom: log scale to emphasize blocking. ... Due to the nature of thin-film interference filters, ...

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/ ...
