OPT-LVS18045-W Arc Light Source – Machine Vision Lighting
Overview of the OPT-LVS18045-W arc light source
In automated visual inspection, three-dimensional defects such as dents, raised burrs or embossed characters on curved surfaces are often very hard to detect without the right lighting angle. The OPT-LVS18045-W arc light source is a new-generation arc-shaped light from the OPT-LVS series by OPT Machine Vision, engineered specifically to illuminate from multiple oblique angles, highlight the 3D information of objects and eliminate the diagonal shadowing that creates noise for inspection algorithms.
As a machine vision equipment distributor in Vietnam, BeeVision supplies the genuine OPT-LVS18045-W arc light along with matching controllers and accessories, helping manufacturers build stable, accurate and highly repeatable visual inspection systems.
What is an arc light source and how does it work
An arc light source has a body curved in a semicircle, with LED strips arranged along the arc projecting light that converges toward the center at an oblique angle. Unlike a ring light that shines straight down, or a dome light that diffuses light omnidirectionally, an arc light delivers controlled oblique illumination, which:
- Highlights 3D information: Oblique light creates shadows and high contrast at edges, grooves and raised characters – helping the camera clearly see surface structure.
- Overcomes diagonal shadowing: The arc shape wrapping around the object removes the one-sided dark zone common when using a single bar light.
- Effectively lights curved surfaces: Ideal for cylindrical components, metal parts and surfaces with complex profiles.
According to OPT’s section structure, the unit consists of: an aluminum housing, a heat sink, a PCB, LED chips and an optional diffuser.
Key features & benefits
Multi-angle illumination that highlights 3D detail
The OPT-LVS18045-W uses 8.4W@24V white LEDs in a semicircular arc with a 180 mm outer diameter for a wide coverage area – ideal for revealing scratches, dents and engraved/embossed characters on curved surfaces.
Flexible diffuser options
The OPT-LVS series allows you to choose from several diffusers to achieve the desired scattering effect: Transparent (high brightness, directional), Standard, and Uniform (soft, low-glare light). This makes it easy to fine-tune for each surface and specific task.
Customizable opening angle and colors
The opening angle of the arc can be customized per application. Besides white light (5000K–7000K), the OPT-LVS series is also available in Red, Green and Blue versions to optimize contrast according to the material.
Robust mechanics, easy to integrate
The aluminum-alloy housing offers excellent heat dissipation in a compact 35 mm section, secured by 3 × M4 holes, 5 mm deep. The JST SMR-02V-B 2-pin connector with an 800 mm cable and 20 mm minimum bending radius is directly compatible with OPT controllers.

Real-world applications
Thanks to its multi-angle illumination that highlights 3D structure, the OPT-LVS18045-W arc light is widely used in:
- Electronic component contour positioning: Determining the position, orientation and contour of components on SMT lines.
- Dimensional measurement of metal parts: Measuring sizes and inspecting the profiles of machined parts.
- Surface defect detection: Revealing scratches, dents and burrs on reflective surfaces.
- Curved character reading: Recognizing embossed/engraved characters (OCR) on bottle caps, can bodies and cylindrical components.
Integration with controllers and vision systems
To get the most out of its performance, the OPT-LVS18045-W should be operated with the OPT-DPA2024E controller – a unit that allows brightness fine-tuning and trigger-based activation synchronized with the camera, keeping captured images consistent from shot to shot and reducing false reject rates.
The OPT-LVS18045-W arc light pairs perfectly with industrial cameras and image-processing software to form a complete inspection solution.
