Digital Optitester model P measures eyeglasses, safety glasses, ski goggles, visors; in detail:
- Refractive properties: spherical and astigmatic power.
- Prismatic power: prism, and prism unbalance.
Conformity assessment of optical parameters is performed vs the following standards: ISO 12312-1:2022 – ANSI Z80.3:2018 – AS/NZS 1067:2016 – GB10810.1:2005 – GB 39552.1 :2020 – JIS T 8141:2016 + Custom defined parameters – EN 166:2001 – ANS Z87.1:2020 – ANS/NZS 1337:2010 – ASTM F 659:10 (2018) – EN 174:2004 – ISO 18527.
Optitester P executes quick and automatic measurement with data output stored in a data base and in a specific testing report.
Software to perform, without human uncertainties, the classification, acceptance or reject of the eyeglasses with friendly visual output pass/fail – green/red display signal. The measurement cycle is 1 second.
Digital Optitester P is equipped with head form that comply the ISO 18526-4 standard.
BASIC FUNCTIONS
Automatic and contemporaneous measurement of optical refractive properties foreseen in the reference standards:
- Sunglasses (ISO 12312-1:2022 – ANSI Z80.3:2018 – AS/NZS 1067:2016 – GB10810.1:2005 – GB 39552.1 :2020 – JIS T 8141:2016 + Custom defined parameters);
- Protection devices (EN 166:2001 – ANS Z87.1:2020 – ANS/NZS 1337:2010).
Measured quantities :
- Spherical power
- Astigmatic power
- Prismatic power
- Prismatic power balance
The criteria necessary to decide whether a product meets the above standards are applied automatically for the acceptance or rejection of a product.
Very smart and quick to use the OPTITESTER can be operated by technicians without specific knowledge of standards requirements and without experience of optical laboratory activities.
Time to carry out a complete measurement is only 3 seconds. All measurements are showed on the screen together to the classification of the eyewear highlighted both graphically and in words.
It is possible to print a test report for each eyewear, save all the measures with the function “save” and save the testing reports.
