Mini Dot Size Red Laser Module Vlm-635-63 Lpo-50, Class 1, Focus At 5Cm APPLICATIONS: Focus point: 5cm. Small Spot Laser module for use with high-precision devices. Medical science. Bio-tech. High-precision 3D scanning. Precision measurement. (For more detail about the laser dot size, please refer to the product pictures.) Product Features High-Quality Industrial-Grade Laser: Designed and manufactured in Taiwan for superior durability and long-lasting performance. Ideal for industrial applications with a 10,000-hour lifespan. This ?Dot Size Laser Module projects a laser dot smaller than 0.04mm at a 5cm distance. (For details, refer to product images.) The laser spot size is measured using a beam profiler, not the human eye. Visual spot size varies depending on the surface material and color?appearing larger on white paper than on black. Due to its 0.04mm spot size at focal distance, halation may cause the dot to appear significantly larger than its actual size. High Precision Applications: Ideal for medical science, biotech, 3D scanning, and precision measurement. Stable Safe Output: Integrated optics, laser diode, and APC (Automatic Power Control) driver circuit to ensure stable laser output. Optimized for a 5 cm focal distance with compact Design: Dimensions: O10.6 x 12.2mm (O0.417" x 0.48"), operating at 3~6 VDC. Wavelength: 630~645nm, Eye-Safe Laser Power Output: 0.39mW (Class I). High Precision Applications: Ideal for Biomedical Research Diagnostics, Metrology Precision Measurement, Optical Alignment Positioning , Machine Vision Systems, Laser Interferometry and Scientific Experiments Laboratory Use.
