IQ Lab™ Temperature Testing for Automotive Lenses

Name: IQ Lab™ Temperature Testing for Automotive Lenses
Brand: Optikos Corporation

Optikos IQ Lab™ Services offers 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.

Lens performance is sensitive to temperature changes
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.

Design advantages of the Optikos^®, Thermal Modules
Our Thermal Module line currently consists of two models, the TM-1150 with a heat exchanger internal diameter of 150 mm, and the TM-1050 with an internal diameter of 100 mm. The TM-1050 is intended for testing relatively small imaging automotive camera lenses, while the TM-1150 is used for measuring larger LIDAR type lenses and imaging lenses mounted in large housings or with large windows attached.

Measurements for a range of temperatures and lens shapes and sizes
Clients can specify the temperature range and discrete temperature points over which they would like their lens to be tested, currently between -20°C and 105°C. IQ Lab lens measurements that can be made at each requested temperature point include MTF, through-focus MTF, and flange focal length.
