As one of the existing functions of the IOL-IMAGER imaging measurement instrument, the brief introduction here is the same as the IOL-IMAGER imaging measurement instrument * and is only for online promotion purposes. Please forgive us!

• The measurement principle of the artificial lens optical eccentricity tester is to place the artificial lens in a fixture with a prescription diameter (10 or 11mm) and measure the offset distance between the geometric center of its optical body and the center of the fixture hole seat.
• The optical eccentricity measurement function of artificial intraocular lens is already included in IM-3 and does not need to be purchased separately.

Artificial intraocular lens imaging measurement instrument IM-3Measurable and Observable:

• Measurable physical properties specified in ISO11979-3 or YY0290.3: axial displacement, optical eccentricity, optical tilt angle (measurable in four directions), contact angle
• Measurable: Lens diameter, outer contour, loop diameter, length, and angle, etc
• Observable: Lens surface quality, defects, knife marks, edge burrs, etc

Artificial intraocular lens imaging measurement instrument IM-3Product advantages:

• One instrument can perform both frontal and lateral measurements.
• XYZ three-axis can move quickly, Z-axis can be fine tuned.
• Provide four independently controlled directional lighting modes: front lighting, back lighting, side lighting, and diagonal lighting.
• The entire measurement process is carried out in a constant temperature water bath, simulating the human eye environment.
• High definition cameras and optical paths provide high-quality images.
• Powerful software provides various measurement and export functions.
