What's the UV/IR Barcode Scan engine?

This is a barcode scan engine architecture specifically designed to directly power and control external add-on illumination boards, such as infrared (IR) or ultraviolet (UV) LED modules.

Unlike conventional designs that require an additional main board to distribute power and manage control signals, CM-2D313 barcode scan engine integrates the light source power supply and on/off control within the scan engine itself.

This allows the external light source to operate in full synchronization with the scan engine without additional trigger circuits or signal routing.

By eliminating the need for a separate main board, the CM-2D313 architecture significantly reduces system complexity, PCB size, and bill of materials (BOM) cost, while simplifying mechanical integration and overall system design.

In most conventional designs, adding a UV LED light source requires an additional main board to supply power and handle trigger signals.This is because typical barcode scan modules are not originally designed with a dedicated interface for add-on light source boards.

As a result, power lines and trigger signals must be routed from the scan engine to the main board, increasing system complexity, PCB size, and component count.The CM-2D313 is designed differently.

From the initial architecture stage, the CM-2D313 integrates dedicated power and control support for external add-on light source boards.This allows UV or infrared LED boards to be connected directly to the scan engine and powered by it, with light on/off behavior automatically synchronized with scan engine operation—without the need for an additional main board.

CM-2D313 Architecture

Scan engine acts as power and control hub
External light source powered directly by scan engine
Automatic light synchronization
Compact system design with lower cost

The add-on UV LED board and IR board are optional.Please clearly specify your selection when placing the order.

About Invisible Barcodes

UV Barcode vs. IR Barcode Comparison

While both UV and IR barcodes serve invisible marking purposes, they differ in durability and material compatibility.

UV Barcode Characteristics

Produces a fluorescent effect under UV illumination
Fluorescence intensity may decrease over time
Prolonged sunlight or UV exposure can accelerate fading
Not suitable for reflective surfaces, such as laser labels, due to strong light reflection and noise

IR Barcode Characteristics

No fluorescence degradation over time
More stable under long-term use and environmental exposure
Suitable for reflective materials, including laser labels
Requires an IR-capable imaging sensor for detection

Shared Limitations

Both UV and IR barcodes are not suitable for uneven or textured surfaces
Rough or embossed materials can distort barcode geometry
Surface height variations may deform module proportions, leading to unreliable decoding or read failure

UV vs. IR Barcode Imaging Characteristics

UV barcodes are typically rendered as inverted images on CMOS sensors, appearing as white bars on a dark background due to UV fluorescence.
In contrast, IR barcodes are usually captured as normal images, showing dark bars on a light background.

Under UV LED illumination, UV barcodes are visually observable.
In contrast, IR barcodes remain invisible to the human eye even under infrared light, but can be reliably detected and decoded by IR barcode scanners.

📘 Invisible Barcode Printing Material Guidelines

Invisible barcodes achieve the most reliable decoding performance when printed on smooth, surfaces. Proper material selection plays a critical role in ensuring stable UV reflection and consistent barcode contrast under UV illumination ( same as IR ) .
