If speed of measurement when checking DIAMETER and SAGITTAL HEIGHT of a soft lens are the main criteria, then the Optimec SAG is your instrument of choice. 
Designed with the large volume lens manufacturer in mind, the SAG is the ultimate fast “in process” dimension checking instrument. 
Used with or without the TC20i temperature and filtration controller, the SAG provides a DIAMETER check facility, as well as a bespoke SAGITTAL HEIGHT measuring function, both from within the unique single chamber wet cell. 
Lens location is quick, simple and automatic thereby minimising the time taken for each measurement. The SAG is available in both 12-15mm and 15-18mm lens diameter variants and each can handle SAG heights up to 6.0mm. 
SAG Height Measurement 
Diameter Check 
Simple and Fast 
12-15 or 15-18MM Diameter Range 
TC20i, TSC3 Compatible 
For temperature control within the cell, we recommend use of the TC20i, or the TSC3 which gives the additional benefit of UV sanitisation. 




The SAG is available in two versions, to measure lens diameters 12-15mm and 15-18mm. Just let us know which version you require. For more details, please Contact Us. 
We are happy to carry-out certified recalibration of the SAG and other Optimec Metrology instruments. Usually this requires the return of the instrument to us, but we are also able to offer calibration and servicing of your Optimec Metrology instruments at your site if required. For more details, please Contact Us. 
Soft contact lens materials expand and contract considerably with changes in temperature. To achieve repeatability of lens measurements, maintaining the cell saline at a constant known temperature is imperative. The Optimec TC20i instrument allows for both filtration and temperature control of the saline in the wet cell. The Optimec TSC3 filters and controls the temperature of the saline as well as reducing the bio burden by means of UV sanitisation. For more details, please Contact Us.
