ZEISS VISIONMES lenses are developed for crucial measuring tasks in industry and feature telecentric optics. For optical metrology at high precision telecentric optics are essential. With this type of objective lens the light is parallel over the whole object field and the image size will remain the same even if the objects position would vary.
ZEISS offers telecentric lenses with outstanding image performance and extremely low distorsion for the purpose of imaging and/or measuring objects up to 300 mm diameter.
Distorsion up to 105 mm object size: 3 µm
Distorsion up to 300 mm object size: 5 µm
TVM is a illumination module for telecentric lenses and works either with Carl Zeiss Visionmes lenses for an object field of 70 mm. It features highly parallel and homogeneous illumination exactly fitting to the telecentric Carl Zeiss Visionmes lenses. Due to its high parallelism* diffraction at the edges is nearly prohibited and the exact detection is considerably improved. As the TVM is designed to be robust and shows several machine seating surfaces it proves to be - in combination with a 70 mm Visionmes lens - an ideally tuned module featuring illumination and objective lens you can easily integrate in your metrology solution.
*The angle to the optical axis is less than 0.1°
Several lens types are only manufactured upon request and with a minimum volume. Please ask always for availability and price.
