In today’s industrial environment, machine vision plays a critical role in manufacturing, inspection, automation, and quality control. However, even the most advanced cameras and image processing software can only perform as well as the optics and lighting used in the system. Choosing the right lens and illumination is essential for achieving reliable, repeatable, and accurate results.
This is where VS Technology (VST), a well-established Japanese manufacturer, stands out. VS Technology specializes in machine vision lenses and LED lighting solutions, developed specifically for industrial imaging applications where precision, stability, and consistency are required.
Machine vision lenses by VS Technology
VS Technology offers a wide portfolio of lenses designed to cover everything from general inspection tasks to highly specialized measurement applications.

High-Resolution Lenses
VS Technology’s high-resolution lenses are designed to fully support modern high-megapixel image sensors. These lenses provide sharp images with low distortion and high contrast, making them suitable for applications such as:
- Surface inspection
- Defect detection
- Fine detail analysis
- Printed pattern and texture inspection
They are commonly used in electronics, automotive, and general industrial inspection systems.

Wide-angle lenses
Wide-angle lenses allow a large field of view to be captured with a single camera. This makes them useful in applications where large objects, assemblies, or wide areas must be inspected without increasing system complexity.
Typical use cases include:
- Large part inspection
- Presence/absence checks
- Area monitoring in automation systems
Telecentric lenses
Telecentric lenses are essential for high-precision measurement and metrology applications. By maintaining a constant magnification regardless of object position along the optical axis, telecentric lenses eliminate perspective errors and ensure accurate dimensional measurements.
VS Technology’s telecentric lenses are commonly used for:
- Dimensional measurement
- Precision gauging
- Edge detection and contour measurement
- High-accuracy inspection systems
These lenses are widely applied in electronics manufacturing, semiconductor inspection, and precision mechanical measurement.

Specialty and application-specific lenses
VS Technology also develops lenses for specialized imaging tasks, including:
- Macro imaging for close-range inspection
- Microscopic inspection of small components
- Custom optical designs for specific customer requirements
These lenses are optimized for particular working distances, magnifications, and sensor sizes, ensuring maximum performance in demanding applications.
Security and surveillance lenses
In addition to industrial machine vision optics, VS Technology offers security and surveillance lenses. These lenses are designed for continuous operation and monitoring applications, combining optical performance with robust mechanical design.
Machine vision lighting solutions by VS Technology
In machine vision, lighting is just as important as the lens. Proper illumination improves contrast, suppresses unwanted reflections, and highlights critical features that may otherwise be invisible to the camera.
VS Technology provides a comprehensive range of LED lighting solutions, specifically developed for machine vision environments.
Ring lights
Ring lights are one of the most commonly used illumination types in machine vision. Mounted around the lens, they provide uniform, shadow-reduced front lighting.
Typical applications include:
- General-purpose inspection
- Surface defect detection
- Presence/absence checks
Diffuse lighting
Diffuse lighting solutions produce soft, uniform illumination that minimizes reflections and glare.
They are especially suitable for inspecting:
- Reflective or glossy surfaces
- Curved or uneven objects
- Printed materials and labels

Bar lights
Bar lights consist of linear LED arrays and are available in various lengths and intensities. They are highly flexible and can be arranged to suit different inspection geometries.
Common use cases include:
- Linear inspection tasks
- Large-area illumination
- Applications requiring angled or directional lighting
Line lights
Line lights provide high-intensity, focused illumination along a narrow line. They are most commonly used with line-scan cameras and in high-speed inspection systems.
Typical applications include:
- Film and strip inspection
- Continuous material inspection
- High-speed production lines
Coaxial lights
Coaxial lighting delivers illumination along the same optical axis as the camera. This makes it ideal for inspecting flat, reflective surfaces, where uniform illumination without glare is required.
Common applications include inspection of:
- Glass
- Wafers
- Polished metal surfaces
- Printed circuit boards

Spot lights
Spot lights provide concentrated illumination on a small inspection area. They are often used together with telecentric lenses or in applications where localized, high-intensity lighting is needed.

UV lighting
UV LED lighting (typically around 365 nm) is commonly used for:
- Fluorescence inspection
- Adhesive verification
- Security marking and ink detection
VS Technology also offers custom wavelengths and sizes for specific applications.

IR lighting
Infrared lighting (commonly 850 nm) is used in applications where visible light is not suitable, such as:
- Seeing through printed materials
- Liquid level inspection
- Certain packaging inspections
Custom wavelengths and configurations are available upon request.
Accessories and controllers
To complete the system, VS Technology offers a full range of accessories, including:
- Diffusers
- Polarizers
- Power supplies
- Controllers
- Cables
These components ensure reliable integration into industrial machine vision systems.
