Following extensive testing and development in our own IQ Lab, Optikos is pleased to announce the release of a new line of configurable Temperature Testing Modules to be used with our OpTest® Lens Testing Systems. This product line has been developed to meet increasing customer demand—particularly from test engineers in the automotive camera market—to evaluate the performance of lenses over extended temperature ranges.
Lens Testing
Our optical testing instrumentation enables us to make a wide range of measurements on optical systems including various measures of image quality, first order system characteristics, individual element parameters, and many more.
Lens Testing over Extended Temperature Ranges
IQ Lab temperature testing services are especially valuable for automotive lens manufacturers and integrators, whose applications have stringent performance and athermalization requirements to meet safety standards for camera image quality. When safety depends on camera and lens image quality, effects such as focus shifts and changes in MTF performance over the operating temperature range of an imaging system can be detrimental if they’re not anticipated in advance. Thermal shifts affecting performance can occur in the lens, in the mounting interface between the lens and the sensor, and in the sensor assembly, and it can be challenging to identify which variable is to blame when a camera system is not performing as expected. Measuring image quality over temperature at the lens level allows our clients to isolate the thermal effects on the lens and adjust other system variables to compensate, if needed.
