Ackermann's technological expertise in creating scopes has developed over many years and even decades as it creates the foundation of their high-quality optical products. The lenses have stainless steel housing to ensure that it will not crack following autoclavation. The proprietary optical design gives excellent illumination, resolution, and depth of field. The Ackermann© patented thermal expansion compenser is more durable than standard solutions. Its scopes make use of lens geometry that is specially made. The lens shapes are generated by a computer and not pre-manufactured. Because of our fiber optic technology, 20% more brightness is offered by a modular system with better focus and depth. Moreover, C-Mount direct coupling is offered. The C-Mount interface guarantees excellent leakproofing and independent scope rotation from the camera head connection.
