Interferometric optimization of lens distances for lens telescopes with three lenses including evaluation

Product Description
Every optical system (like a telescope) achieves its maximum performance when its design is implemented with sufficient mechanical precision. This means that if certain deviations occur during the telescope's production, or during transport from the manufacturer to the dealer and then to the customer, the image will be subject to errors. For example, coma, chromatic aberration, spherical aberration, astigmatism, and a combination of all of these. Even if the telescope was optimally adjusted during production, the lens can slip within the lens cell during transport. These errors are not always visible or noticeable during visual observation. They only become apparent during astrophotography, with longer exposures.

We can correct some of these deviations during our inspections and optimizations (which we always perform before delivery to the customer), but we cannot correct the distance between the lenses with our resources.

We work with companies that have the necessary equipment and measuring technology. The system-relevant, optimal lens spacing and centering in the lens cell are determined interferometrically and permanently adjusted. This means that even subsequent transport will not cause any further changes.

This is comparable to chip tuning in a car. When the car is delivered from the factory, it will have sufficient power, but the tuning extracts the maximum possible performance from the engine.
