150mm, f/4 Athermal Lens

Product Details Designed to Maintain High Resolution Over a Wide Temperature Range Ruggedized for Shock and Vibration Environments Large Sensor Coverage up to 1.1” Optothermal Stability from Passive Athermalization 2022 Silver VSD Innovators Award Winner and 2022 Inspect Award Winner TECHSPEC Athermal Imaging Lenses provide optothermal stability in a ruggedized lens housing, making them ideal for harsh environments. These lenses utilize passive athermalization to mitigate the effects of thermal defocus in applications that are prone to temperature fluctuations. Additionally, these lenses are ruggedized to protect against lens damage and minimize pixel shift after shock and vibration. Along with being ruggedized to protect against lens damage and minimize pixel shift after shock and vibration, these lenses are thermally compensated and best used with camera mounts made from aluminum. TECHSPEC Athermal Imaging Lenses feature C-Mount threading and full coverage of sensors up to 1.1”. These lenses won the 2022 Silver VSD Innovators Award and the 2022 Inspect Award. Note: Passive Athermalization is introduced in the application note here.
