Frequently Asked Questions
What sensor size does the PMS-LFCH-4.528M(J) support?
It supports sensors up to 1/1.8" (9mm), and is also compatible with smaller formats such as 1/2".
What is the distortion of this 4.5mm lens?
The distortion is approximately -1.2% at y=4.5mm on a 1/1.8" sensor, keeping wide-angle imaging geometry stable.
How close can this lens focus?
The focus range is 0.1m to infinity, so it covers both close-range wide-FOV imaging and distant scenes.
Can the iris and focus be locked?
The iris (F2.8-F16) and focus are manually adjusted; after setup, settings stay stable in typical industrial environments.
