VS-TLS (FR) series is new VST’s concept lens can fit various optical magnification required by the customer by dividing the front lens and rear lens into two parts and multiplying them. Environmentally friendly product design that enables reduction of costs incurred by specification changes after installation. To ensure performance in a variety of application environments, front and rear coupling structure, with unique locking ring configuration (X lock system) ensures lens accuracy and function ring that holds the lens allows adjustment of the holding plate and camera position.

• Wide field of view, high telecentricity
• Low distortion to the periphery
• Up to 20 different optical magnifications can be achieve by freely combining  4 front models and 5 rear models.

Fit-X  (Fit-Cross)

By separating the front and rear lenses into two parts and adjusting them by a factor of -X-, VST’s innovative lens design can accommodate various optical magnifications as per the customer’s requirements.

X Lock System

Function Ring

This ring is made to securely connect a plate supporting the lens without requiring a jig to grip the lens body, thus minimizing any negative effects on performance. By rotating the Function Ring, both the holding plate and the camera’s position can be adjusted beforehand, lessening the necessity of repeatedly attaching and removing the lens for precise adjustments.
