4K entails a resolution of at least 3840 x 2160 pixels and this represents a fourfold increase compared with the existing HD standard. In order to get this pixel power on the road, Richard Wolf with its long tradition of innovation has strategically bundled all of its in-house expertise: telescope, light, signal processing and the latest production technology melded into one system, providing a solution from a single source.
Optical systems and light cables: Optimum match guaranteed
The new sharp begins with the completely new telescope developed in-house for the rigid 10 millimeter endoscope. This generates a homogeneous, illuminated image with sharp margins. Specially doped glass material is used for the lenses to minimize any optical errors. The light source plays an important role in implementing the new sharp. The latest light cables with correspondingly high transmission and a powerful LED light sources are used for the 4K version. The light power therefore keeps pace with the increase in resolution. It is precisely tailored to the requirements of the new camera system.
Lower power consumption reduces development of heat
The new compact is manifested in the ergonomically shaped camera head with reduced dimensions and weight. Richard Wolf uses a new generative method here in order to manufacture the metallic camera casing utilizing a 3D printing process. The result is that the camera head is a comfortable fit in the user’s hand and it is also tangibly lighter. The stainless-steel material can be autoclaved and is ideal for chemical sterilization procedures. It is therefore classified as sterile and may be used without the need for any additional covers. Richard Wolf reaches a new level of efficiency as a result of the reduced power consumption in various areas. The LED technology demonstrates significant savings over the previous gas discharge lamps. At the same time, the company has succeeded in using more powerful and very efficient electronic components in the camera head. It consumes around 30 percent less electricity and this is demonstrated in a significantly lower development of heat.
Precise image of reality without extrapolation
The advantages of the system from a single source continue behind the camera head since the powerful signal handling processes the 4K signal in the original resolution for the new authentic. Cables, connectors and controllers are consequently designed so that the significantly expanded data volume is free of loss. This increases the failsafe performance and the faithful visualization of the original image – very much the new authenticity. At the same time, Richard Wolf has the experience and the ability to generate additional benefits from the surveyed data. Special visualization processes improve tissue differentiation, illuminate critical areas of an image, and clearly visualize structures situated in bright but overexposed regions.
