Product Application

35. LED Optical Lens: 15° Collimator Lens for COB This 15° collimator lens (30mm diameter) focuses COB LED light into a narrow beam, ideal for spotlights or projectors. Made from PMMA (92% transmittance), it features a micro-structured surface to reduce glare. Technical specs: heat resistance up to 85°C, snap-in installation for 35mm COB modules, and anti-yellowing treatment. Suitable for stage lighting, automotive headlights, or industrial indicators. 36. Parabolic Mirror: 500mm Parabolic Reflector The 500mm parabolic mirror (focal length 250mm) features an aluminum-coated surface (96% reflectivity), focusing parallel light to a precise point. Ideal for solar cookers, telescope primaries, or searchlights, it withstands temperatures up to 250°C. Technical specs: 1.5mm thickness, CNC-machined frame, and mounting brackets for easy installation.

37. Fresnel: 200mm Plastic Fresnel Lens for Solar This 200mm Fresnel lens (focal length 400mm) concentrates sunlight for solar power or heating, made from UV-stabilized PMMA (90% transmittance). The lightweight design (200g) is 70% lighter than glass, with 1mm thickness. Technical details: 120° acceptance angle, scratch-resistant coating, and compatibility with solar cells or thermal collectors. Used in DIY solar projects, greenhouses, or educational kits. 38. Fluorescence Microscope: Benchtop Fluorescence Microscope This benchtop fluorescence microscope uses 470nm (blue) and 550nm (green) LED excitation, with 40-1000X magnification (10X eyepieces, 4X-100X objectives). Equipped with a 5MP camera and software for image analysis, it supports fluorescence and brightfield modes. Technical specs: 1.25mm resolution, mechanical stage, and 110-240V power. Ideal for biology labs, pathology, or material science.

39. Optometry: Auto Refractor-Keratometer This auto refractor-keratometer measures refractive errors (sphere, cylinder, axis) and corneal curvature (K readings) with 0.01D/0.01mm precision. The 8-inch touchscreen displays results, with a built-in printer and patient database. Technical specs: 1000+ measurements/hour, infant mode, and PD measurement function. Streamlines optometry exams in clinics or hospitals. 40. Lens Polishing Machine: CNC Lens Polisher Designed for precision optics, this CNC lens polisher achieves <0.5nm surface roughness via diamond slurry and programmable speed (5-3000rpm). The 5-axis system processes convex/concave lenses (10-300mm diameter) with 0.005mm positional accuracy. Technical specs: water cooling, dust collection system, and compatibility with glass, PMMA, or crystal. Used by lens manufacturers or research labs for high-precision optics.
