Request InfoDelta Optical Thin Film A/SOptical thin-film maker Delta’s new line of linear variable order sorting filters features wide transmission and reflectance bands, increasing the performance of grating-based spectrometers. The company offers a linear variable long-wave pass filter and the corresponding linear variable short-wave pass filter, together with a linear variable dichroic. The filter types can be used separately, while combining the two types enables the construction of bandpass filters that can be tuned continuously with center wavelengths from 320 to 850 nm.
