Our standard filters are produced in quantity (and used in our standard detector systems) and we are able to offer these at a better price than non-standard filters.
Our standard band-pass filters have the following properties (other filter designs are available on request):
The measured transmission spectra are shown below:
Our standard low-pass filters have the following properties (other designs are available on request):
The performance is demonstrated below using the measured transmission spectrum of our 9 THz design. The graph below shows that the average in-band transmission efficiency is 85% or better.
Out-of-band blocking is better than 0.1% over a very wide range of frequencies out to the optical region, as shown in the graph below.
