180 Degree 830nm 300mW Infrared Line Laser Module for Smart Touch Projector

180 Degree 830nm 300mW Infrared Line Laser Module for Smart Touch Projector This 180 Degree 830nm 300mW Infrared Line Laser Module is a professional core component tailored for smart touch projectors, integrating ultra-wide 180° line projection, 830nm infrared anti-interference performance, and 300mW high-power output. It projects uniform infrared lines to form a dense touch sensing grid on projection surfaces, enabling accurate, fast touch interaction for home, commercial, and educational smart touch projectors—becoming a key part in realizing large-size, multi-touch projection control. Core Technical Advantages for Smart Touch Projectors – 180° Ultra-Wide Line Projection: Adopts a custom optical diffuser lens to achieve a full 180° projection angle, covering projection surfaces up to 120 inches (diagonal) without blind spots. This eliminates the need for multiple laser modules, simplifying smart touch projector optical design while ensuring seamless touch coverage across the entire screen. – 830nm Infrared Anti-Interference Optimization: The 830nm infrared wavelength avoids interference from ambient light (sunlight, LED lighting) and projection light sources. It ensures stable infrared line recognition even in bright environments, preventing false touches or touch lag—critical for reliable touch interaction in classrooms, meeting rooms, or home theaters. – 300mW High Power for Uniform Line Output: With stable CW output (power fluctuation ≤±3%), it projects a high-contrast infrared line with uniformity across the 180° range. The line width remains controlled at <2.5mm@2m, ensuring the smart touch projector’s CMOS camera captures clear line signals for precise touch positioning.
