Product Description

Labgear NSC4 4-Head UV LED Spot Curing System

provides fast, controllable UV LED spot curing on 4 independent channels. It is a compact, production-ready UV LED spot curing system built around a 4-channel controller and four independently adjustable LED heads. Configure each channel for the wavelength, optics, intensity, and timing you need—then repeat it reliably across a bench process, work cell, or automated systems.

See our quantity discounts for multi-station deployments.

Applications

UV adhesive & resin curing:

• Spot curing UV adhesives, encapsulants, and repair resins
• Localized curing in fixtures where masking or heat control matters

Coatings, inks, and marking:

• UV inks and coatings for small-area processing
• Stamp/mark illumination workflows and re-entry stations

Fluorescence excitation & inspection:

• Exciting fluorescent dyes and tracers for inspection and analysis
• Leak detection workflows using fluorescent indicators
• Various wavelengths can be used to excite fluorescence in dyes, minerals, and biological samples, which is particularly useful in fluorescence microscopy, flow cytometry, and other analytical techniques.

UV Curing in 3D Printing:

• UV LEDs are utilized in some 3D printing processes, particularly those that involve photopolymerization. The UV light selectively cures layers of resin to build up a three-dimensional object.

Automation and multi-station cells:

• Sensor-triggered curing/exposure using external I/O and synchronized control
• Multiple heads across a bench line or compact cell

Features 

• 4 independent channels (run one, some, or all channels as your process requires)

• Multiple wavelengths: 365 / 385 / 395 / 405 nm options

• Interchangeable spot optics for quick beam-size changes (3–15 mm options)

• Manual, timed, and multi-step cure profiles (STEP mode) for better process control

• Automation-ready: footswitch + external I/O terminal + RS232 interface

• Simple location and isolation with LED head cable lengths up to 15 meters (50 ft), 

• Higher thermal efficiency heat sink fins and even a fan option are available to maximize lifetimes of both LED and LED driver electronics for use in demanding industrial production environments.

• Each channel can be run in: Manual (on/off), Automatic (timed exposure), or STEP (multi-step exposure) modes.

  • Configurable head styles: compact head option plus higher thermal-efficiency heads (including a fan-cooled option)

  • Repeatable operation: save settings, lock them, and use external triggering when needed

• The ability to customize and mix configurations, and with independently adjustable control of each channel and the selection of mixed LED wavelengths and lenses, will allow for an optimized excitation, detection or curing process, beam shape, intensity, timing, and system geometry or locations.  

• Comparison of NSC4 vs typical 4-channel UV LED spot systems

  Capability that matters in real production	How NSC4 addresses it
  Multi-stage cure control (beyond simple on/off or single timer)	STEP mode supports multi-step intensity/time profiles and repeat cycles for process tuning.
  Automation integration without custom electronics	External I/O terminal supports channel start/stop inputs and READY/BUSY/ERROR outputs; RS232 supported for controller communication.
  Preventing “mystery drift” from bumped settings	Keyed parameter setting + lock options help maintain validated settings for quality and process control on the floor.
  Spot size flexibility for R&D → production transfer	Interchangeable optical lenses for beam-size changes without replacing the entire head.

Specifications

• Key Usage Differentiators

  • True channel independence: set different intensity/time per head—useful for multi-station fixtures, rework stations, or mixed materials in one cell.

  • STEP mode cure profiles: program multi-stage exposure (ramp/soak strategies) to improve cure quality and reduce heat/over-cure risk on sensitive parts.

  • Keyed settings lock: lock parameters to prevent accidental edits after validation.

  • External control and status signaling: integrate with sensors/PLCs using start/stop inputs and READY/BUSY/ERROR outputs for hands-free operation.

  • Maintenance visibility: per-channel accumulated irradiation time + clear error codes for faster troubleshooting.

• What you get in the box: Integrated 4-channel LED controller + four UV LED heads on cables with interchangeable optics + Footswitch + Safety Glasses + Set of Keys

• Safe Operation: UV light can be hazardous—use appropriate PPE and follow the operating manual.

• Warranty: Full 2 year warranty on all systems and components from the original invoice date. Coverage is limited to repair and/or replacement at the manufacturer’s option. Warranty may be void if the product is modified, misused or damaged.  Any disassembly of the controller or LED head shell without written authorization voids warranty. 

• Additional Spot Lenses for quick maintenance, spares, beam-size changes and engineering experimentation

• Additional Cable Heads on cables, with and without lenses, and including fan-cooled option as needed)

• Elongated/line optics available (Contact us for information)

• Option for 90° Angle output from head (Contact us for information) 

FAQs

Can I run different curing settings on each head?

Yes. NSC4 supports four independent channels so you can set different mode/intensity/time per head and run channels independently or together (with LINK settings if desired).

What’s the difference between Manual, Automatic, and STEP modes?

Manual is on/off control, Automatic adds a timed exposure, and STEP mode allows a multi-step profile (1–16 steps) where each step has its own intensity and time. STEP mode can also repeat for 1–99 cycles to match your validated process.

How do I integrate NSC4 into an automated station or PLC?

Use the 24P terminal for channel start/stop inputs and READY/BUSY/ERROR outputs. Start behavior supports either PULSE (toggle) or LOW (level-synchronized) control. RS232 is also available when serial control/monitoring is preferred.

What spot sizes are available, and how do I change them?

Choose the UV beam size option when ordering, and use replacement optical lenses to change spot size as needed. Lens choices affect spot size, focus distance, and delivered irradiance.

What does the keyed lock do?

The controller includes a keyed setting function: when the key is ON you can edit parameters; when it is not ON you can still run irradiation, but settings cannot be changed—helpful for preventing accidental process drift.

What safety precautions should I plan for?

UV light can be hazardous. Use appropriate protective glasses/face shield/clothing, ensure grounding, and maintain clearance for cooling per the operator’s manual.
