Koh Young offers the Revolutionary True 3D Dispensing Process Inspection (DPI) with a Thickness Measurement Solution based on Patented Technologies
Most optical systems use UV light to inspect the surface for presence and gauges to measure material thickness in a particular spot, which does not provide the accuracy and repeatability needed. Inspecting transparent materials proved to be a challenge for traditional laser-confocal or electron microscope systems that only measure three-dimensional shapes.
Koh Young’s revolutionary Neptune provides the ultimate solution to these challenges.

Neptune T
The industry’s first 3D optical measurement instrument for transparent material
- Non-Destructive Inspection with True 3D Profiling
Koh Young developed a non-destructive thickness measurement solution for transparent materials. The system allows manufacturers to explore depths of its process and accurately identify defects with 2D, 3D, and cross-section views. - Superior Performance – L.I.F.T Technology
The Koh Young L.I.F.T technology delivers non-destructive 3D inspection to precisely measure and inspect fluids that are wet or dry. Based on low-coherence interferometry, L.I.F.T. employs Near Infrared (NIR) Light to capture images through multiple layers of a fluid structure regardless of transparency. This patented technology provides the most accurate and reliable 3D inspection across any surface – Smooth, uneven, or rough. - From Lab Testing to Industrial Inspection
Not limited to conformal coating, the Neptune T measures underfill, epoxy, bonding, glue, and more to deliver an accurate measurement of transparent, translucent, and pigmented materials. The system is currently suited for acrylic, silicone, polyurethane, water-based, UV- cure, and hybrid coatings with additional materials being investigated.The Neptune T handles several types of applications from research labs to high volume production.

Neptune C+
Revolutionary True 3D In-line Dispensing Process Inspection (DPI) with a Thickness Measurement Solution based on Patented Technologies
- True 3D Profiling
Koh Young developed a non-destructive thickness measurement solution for transparent materials. The system allows manufacturers to explore depths of its process and accurately identify defects with 2D, 3D, and cross-section views.
The system accurately measures materials for coverage, thickness, and consistency with user-defined threshold setting. It also inspects bubbles and other defects as small as 200-micros, even inspecting “keep out” areas for 100-micron splash marks. - Superior Performance – L.I.F.T Technology
The Koh Young L.I.F.T technology delivers non-destructive 3D inspection to precisely measure and inspect fluids that are wet or dry. Based on low-coherence interferometry, L.I.F.T. employs Near Infrared (NIR) Light to capture images through multiple layers of a fluid structure regardless of transparency. This patented technology provides the most accurate and reliable 3D inspection across any surface – Smooth, uneven, or rough. - AI-Powered Capabilities
With its proprietary machine learning technology, the Neptune C+ offers enhanced inspection capabilities enabling autonomous bubble inspection without teaching and endless tuning. - High Throughput
Not limited to conformal coating, the Neptune C+ measures underfill, epoxy, bonding, glue, and more to deliver an accurate measurement of transparent, translucent, and pigmented materials. The system is currently suited for acrylic, silicone, polyurethane, water-based, UV-cure, and hybrid coatings with additional materials being investigated. The Neptune C+ handles several types of applications from research labs to high volume production. - Simple, Intuitive Programming
The Neptune C+ programming software provides a hands-on user interface, which emulates a simple raster graphics editor to allow intuitive programming with great flexibility. Programming is further simplified with our wizard-based graphical user interface. All parameters can be adjusted for quick setup and fast changeovers. - Top & Bottom Inspection with a flipper
Koh Young offers a function that inspects both the top and bottom of PCBs with a flipper option. - Fully Automated In-line Inspection for Extra-long Applications available
Koh Young offers a perfect solution for extra-long boards like LED lighting up to 1,300mm, which can be extended up to 1,800mm with a long board option.
