Description
The Elegoo Fresnel Lens is an official OEM optical element engineered specifically for the light source system of the Elegoo Saturn 4 Ultra resin 3D printer.
Positioned directly above the COB (Chip-on-Board) UV light source array, this precision optical lens collimates and refracts UV light at a 405nm wavelength. By channeling the light rays into a parallel beam across the entire 12K monochrome LCD screen area, it eliminates light scattering and vignetting at the build plate edges. This ensures uniform light intensity distribution, crisp pixel edge definition, and precise layer curing for high-detail, large-format resin prints.
Features
Collimated Parallel Light Beam: Refracts UV light into a strictly parallel output angle, drastically reducing light bleeding and pixel blur.
Uniform Light Distribution: Eliminates central hotspots and edge drop-off, providing consistent resin curing across the entire build area.
High Optical Transmittance: Manufactured from optical-grade resin/polycarbonate designed to maximize 405nm UV light transmission while resisting long-term yellowing and thermal degradation.
Direct OEM Fit: Precision-cut to fit the internal mounting bracket of the Saturn 4 Ultra optical chamber, ensuring drop-in alignment with the COB UV light engine.
