The term “V-COT lens” does not appear to be a widely recognized or standard term in the field of optics or lens technology as of my last update in January 2022. It’s possible that it could be a specialized or proprietary term specific to a certain company, product, or industry niche that has emerged since then. Without further context or information, it’s challenging to provide a specific explanation of what a “V-COT lens” might refer to.
If you have additional context or details about where you encountered this term or its intended application, please provide them, and I’ll do my best to offer relevant information.
