High-performance optical thin film components

Delta Optical Thin Film A/S

An extended set of performances within one single filter! A Linear Variable Filter (LVF) is a wedged filter, whose spectral properties vary linearly. A single LVF for example can replace a number of dedicated filters in an instrument. It is possible to adjust the position of the edge by sliding the filter. Each of the filters can be used separately. Combining LVLWP and LVSWP enables the construction of band-pass filters that can be tuned continuously with center wavelengths from 320 nm to 850 nm, with the added benefit of tunable bandwidth.
