Lens after puncture test (different materials)

Product features:

• It can measure conventional soft contact lenses (of various materials and designs) and other special functional lenses (such as artificial corneas).
• The upper and lower fixtures adopt special processing technology to ensure that the curved surface in contact with the lens can provide sufficient friction to firmly clamp the lens during the testing process and prevent it from moving.
• Using the principle of fixed pressure with weights, it ensures that each lens can receive consistent clamping force and can be replaced with weights of different weights according to different lens materials.
• The transparent fixture system allows for visualization of the lens installation and testing process, and reserves inlet and outlet ports for expansion into a constant temperature system.
• It can directly measure the force value at the moment of lens rupture and the deformation value at the time of rupture..
• The test curve is directly displayed on the computer, and all test data can be exported and saved for further analysis.
• Adopting a high-sensitivity S-shaped force sensor customized from abroad, it has excellent repeatability, ensuring stable and reliable test results.
• Equipped with weights that can be verified, calibrated, and traceable.
• Easy to operate, the touch screen LCD provides a friendly human-machine interface, and the software interface functions are more powerful.
