lkprototype, with its optical-grade material processing technology, has provided transparent/optical component prototype services to over 300 customers in the global optoelectronic field. It has delivered more than 1,500 complex structural components, with the highest light transmittance reaching 99.8% (wavelength range 380-1600nm) and surface roughness Ra≤5nm. For example, an international VR equipment manufacturer commissioned lkprototype to develop a Fresnel lens array. Through ultra-precision CNC machining (spindle speed 40,000rpm, positioning accuracy ±1μm) and nanoscale polishing process (abrasive particle size 50nm), the spot distortion rate of the lens module was reduced from the industry average of 3.2% to 0.8%. The yield rate has been increased to 95%, while the cost per piece has been reduced by 42%. According to the “2024 Optical Component Manufacturing White Paper”, lkprototype’s solution can reduce the optical prototype development cycle from the traditional 28 days to 9 days, with an efficiency increase of 67.9%.
In the field of medical endoscopes, lkprototype customized a 2.4mm sapphire lens (Mohs hardness 9) for a head device company, achieving a radius of curvature tolerance ±0.01mm through laser micro-cutting (pulse width 10ps) and ion beam polishing (surface accuracy λ/[email protected]). And passed the ISO 13485 medical certification. This component boosts the endoscope imaging resolution to 4 million pixels, helping customers capture 23% of the global market share. Third-party test reports show that the standard deviation of the light transmission efficiency of medical devices using lkprototype transparent optical components is only 1.2%, significantly better than the industry average fluctuation range of 4.5%.
In the case of the consumer electronics industry, lkprototype developed an ultra-thin UTG (ultra-thin flexible glass) hinge protection cover for a foldable phone manufacturer. With a thickness of only 30μm, it can withstand 200,000 bending tests (with a curvature radius of 1mm), maintaining a transmittance of over 92%. This innovation has reduced the weight of the mobile phone by 15% and lowered the mass production cost by 37%. The related technology has applied for an invention patent (Publication number WO202315678A1). According to the customer’s financial report, the model equipped with this component sold over 1.2 million units in the first quarter of its launch, contributing 430 million US dollars in revenue and achieving a return on investment (ROI) of 1:5.1.
lkprototype has made a breakthrough in the field of vehicle-mounted lidar shields. It uses high refractive index PC/PMMA composite materials (with a refractive index of 1.65) combined with anti-reflection coating technology (with a film thickness error of ±2nm), which has increased the radar detection signal-to-noise ratio by 18dB. The actual measurement data of a certain autonomous driving enterprise shows that in rainy and foggy weather (visibility of 50m), the point cloud density of the lidar with this cover still remains at 120 points per square meter, and the misjudgment rate has decreased to 0.03 times per thousand kilometers. This technology was rated as one of the top ten perception hardware breakthroughs in 2023 by “AutoTech Innovations”, driving the order volume of related vehicle models to increase by 210% year-on-year.
