Frequently asked questions
The JCF is calibrated by using the test button provided with each new instrument. A calibration video can be seen clicking the video tab and selecting the calibration video. For more details please contact us.
We are able to supply standard replacement plastic test buttons and also certificated glass test buttons for the JCF. These are available in a range of sizes. For more details please contact us.
The original halogen lamp fitment (soon to become unavailable) has now been superseded by a specially designed LED light engine which is now fitted as standard to all new Optimec instruments. The LED provides a whiter light, sharper images, cooler operating temperature, and lower running costs. The LED has been designed so it can be retrofitted by the customer to the majority of older instruments. Contact us.

The Optimec model JCF has been designed for laboratory and quality assurance department use. The design brief being to manufacture an extremely accurate instrument for BCOR and DIAMETER measurement with surface and edge inspection facilities. Excellent projection lens acuity gives very clear imaging of the edge and surfaces of the contact lens under examination. When the JCF is used to measure BCOR, the lens locator is essential for quickly locating the contact lens upon the measuring cylinder. Diameter measurement and lens surface inspection is also fast in use as the lens is placed in a “V” graticule assembly where the forward tilt allows the lens to settle quickly under the influence of gravity.
