Linear Transmittance Filter Tutorial
Linear Transmittance Filter (LTF) has a transmittance that is changing linearly over a specified wavelength range. LTFs are typically used for…
Single Cavity Filter Tutorial
The Single Cavity Filter (SCF) is used to select a single frequency from a broad spectral range. SCFs are typically used for…
Etalon Tutorial
A Solid Etalon Filter (SEF) is used to select a periodically spaced frequency grid from a broad spectral range. The key specifications
Band Pass Filter Tutorial
Band Pass Filters (BPFs) are used to pass (transmit) a range of wavelengths and to block (reflect) other wavelength on either side of the bandpass. The region of high transmittance is known…
