신뢰성 & 정밀성

 CHRocodile-시리즈 광학 센서들로 접촉 없이 고도로 정확하게 의료 장비 부품들의 거리와 코팅 두께를 측정할 수 있습니다. 예컨대 의료 풍선들의 정확한 벽 강도는 치료 성공에 지극히 중요합니다. 안경 유리와 콘택트 렌즈의 경우에도 가공 중에는 최고도의 정확성이 필요합니다. CHRocodile-센서들은 안경 유리의 유리 두께와 긁힘 방지층 두께를 측정합니다. 포장 분야에서는 포일,블리스터, 몰드 등에 대한 높은 품질 요구 수준들을 당사의 정밀 측정 기술로 만족시킵니다. 센서들은 나아가 기타 많은 의료 응용 분야, 예컨대 인공 고관절과 무릎 관절 및 스텐트의 고정밀 측정 시에도 효과를 입증하였습니다.

Wall thickness of hoses for medical applications, coatings

The wall thickness of transparent hoses for medical applications can be measured well with interferometric measuring methods. It depends on the individual case whether the thickness of individual layers of multi-layer hoses can also be measured. This may depend on the difference in the refractive indices of the individual materials. If the refractive indices of the materials differ sufficiently from each other several individual layer thicknesses can be measured. The thickness can also be determined for materials which are not transparent to white light– e.g. coloured hoses. In this case measurements are taken with infrared light. In the field of medicine, the thickness of ventricular pump membranes is also measured with chromatic confocal sensors. Optical contact-free measuring systems are also used for measuring the wall thickness of balloons which are used in angioplasty. Up till now, wall thicknesses have been measured mechanically using a micrometer through two wall thicknesses and then the result halved. These procedures are, therefore, only accurate within certain limits. Stent coatings can be measured interferometrically.

Measuring the wall thickness of glass flasks with low wall thicknesses

Glass capillaries are thin glass tubes with an internal diameter of approx. 0.1 - 1 mm. Because of the low internal diameter, capillary forces are created which cause liquids, such as blood for example, to be sucked up. Injection flasks are small glass flasks with a capacity of a few milliliters. They are closed by an injection plug or a penetrable membrane.

The wall thickness of these thin tubes or glass flasks can be measured very accurately and, most importantly very quickly, with contact-free optical measuring methods that make it possible for them to be used in inline measuring systems.

Here Precitec Optronic interferometric sensors are often used. The wall thickness can be measured within a few microns. The lateral resolution is in a single figure μ range. Topographies can be determined very quickly with a line sensor like the CHRocodile CLS which enables the depth and width of cracks in the glass surface to be measured, for example.

Measuring liquid layers and liquid levels

In medical engineering, the oil thickness on hoses of injection needles or venous catheters is important. The thickness of the oil layer can thus be determined using contact-free optical measuring systems. This layer thickness can be determined within a few microns. Should the objects not be evenly moistened, the places with or without oil can be detected. This technique has also been proven when pipetting microtiters. If these are filled automatically, a confocal sensor can measure the distance between the sensor and the liquid surface in another also automated step. The fill quantities for larger runs can be very quickly calculated from this measurement.

Contact-free 3D measuring systems for endoprostheses

The complex, multi-curved geometries of endoprostheses have tolerances between a few microns up to several hundred microns. Their highly reflective surfaces pose considerable problems for optical measuring systems. The surfaces of the material pairs must be produced in the required quality. Here ultra high molecular polyethylene and metals or ceramic on the other side are used. If parts with these sizes are to be measured in 3D, you need sensors that can record the very different surfaces without losing accuracy. The high apertures of chromatic confocal optical probes ensure that sufficient light from the highly reflective free form surfaces reaches the sensor. Retrieval analysis is an important area of activity as well as quality assurance in production. These analyses are mainly used to understand why wear occurs. Using prostheses that have recently failed in use and have not reached their estimated service life, they try to find the causes.
