Filter testing

Filter measurement: have your filters evaluated

Amateur astronomers are often uncertain when buying a nebula filter. Am I buying a high-quality filter? Does my filter enable the correct wavelengths to pass through? Anyone buying a nebula filter will be interested in these questions. After all, who doesn't want to ensure maximum performance while observing?

Let us test your filters for you. We have a state-of-the-art UV-Vis spectrometer in our optical workshop. With this, our experts can exactly determine the transmission curve of your filter. You will receive a personalised test report: the best proof that your filter is allowing the correct wavelengths to pass through.
