Square Precision Optical Diffuser
Our Square Series optical diffusers are the preferred solution for projects requiring symmetric beam shaping and wide-angle homogenization. By utilizing high-purity glass substrates such as B270, EXG, and White diffusing glass, these components deliver exceptional clarity and light throughput. The square geometry is specifically engineered to maximize the effective illumination area in rectangular optical paths, providing a robust and reliable interface for advanced machine vision and laser processing.

Product Features
- Versatile Substrate Compatibility: Engineered from a range of optical-grade materials, including Corning EXG/CG for thermal stability and B270 for high visible transmission.
- Superior Diffusion Consistency: The specialized translucent matte finish ensures a “hot-spot free” output, successfully blending point light sources into a perfectly uniform area light.
- Precision-Machined Edges: Each diffuser features expertly ground edges with chipping controlled under 0.3 mm, ensuring high mechanical strength and safe handling.
- Strict Surface Metrology: Every unit undergoes rigorous inspection to ensure surface defects remain well within the 60-40 or 40-20 Scratch-Dig range.
Detailed Description
Engineered Material Excellence:
- White diffusing glass & B270 Glass: These materials are selected for their neutral color balance and superior transmission, ideal for broad-spectrum lighting and high-end commercial displays.
- EXG & Specialty CG Glass: Known for their ultra-pure composition and low expansion coefficient, these are perfect for high-intensity laser systems and precision medical diagnostic tools.
- Advanced Manufacturing Standards: Our commitment to quality is reflected in our strict control over physical imperfections. By limiting scratches to < 0.06 mm and pits to < 0.4 mm, we ensure that our diffusers minimize diffraction artifacts and unwanted glare, even when utilized in high-sensitivity imaging sensors. The precision-finished edges further guarantee that the square diffusers can be securely integrated into tight-tolerance mechanical assemblies without risking structural integrity.
Typical Applications:
- Machine Vision & Inspection: Used to create even, shadowless illumination for high-precision surface defect detection.
- Laser Beam Homogenization: Converts non-uniform Gaussian laser profiles into flat-top intensity distributions.
- Flat Panel Backlighting: Enhances the uniformity of LED arrays for displays and signaling devices.
