Every unit, every batch
Nothing leaves the building without a test record. The record is tied to the serial number marked on the barrel, so a replacement ordered long after the original can be checked against the same build standard.
Optical performance testing
Every lens is measured on our own benches for sharpness and contrast, both at the centre of the image and towards the edges, and must meet the published acceptance level before it ships.
Geometry checks
Each lens is checked against a certified reference target to confirm that the image geometry matches the specification. Correction data for measurement applications is available on request.
Measurement accuracy
For measurement lenses we verify that the scale of the image stays constant as the part moves slightly closer or further away, and we report the worst-case figure rather than the average.
Environmental testing
The first units of every design are tested across the full operating temperature range, and against vibration levels typical of a machine-mounted installation.
What you receive
The datasheet and the test record for your serial number. Ask and it is sent — there is no charge and no paperwork required for your own unit’s data.
