Linear Transmittance
Linear transmittance filters (LTF) are used for wavelength identification applications, employing a transmittance that changes linearly over a specified wavelength range. The LTF transmittance must be monotonic to provide a one-to-one correspondence between the filter transmittance and a given wavelength.
Iridian is experienced in the design and manufacture of numerous linear transmittance filters. They feature low substrate-etalon ripple, custom slope and dynamic ranges with low linearity tolerance.
In addition to the standard LTF, Iridian can custom-manufacture these filters to your specifications.
