- Using a Right-Angle Prism for TIR? Master These 3 Physical Details First 7/20/2026 In optical design, the right-angle prism is a component that appears simple yet is remarkably sophisticated. It leverages the principle of total internal reflection (TIR) to achieve optical path folding with extremely low loss — a characteristic that makes it an "upgraded alternative" to conventional mirrors. However, to truly harness the full potential of a right-angle prism, several critical phy...
- Detection and Polishing Suppression of Subsurface Damage in High-Power Lenses 7/13/2026 In high-power lasers (>1kW), lenses with intact coatings may suddenly crack and experience a sharp drop in lifespan. The culprit is often not surface defects, but rather subsurface damage (SSD) hidden beneath the surface—a network of microcracks left by grinding. Under intense light, this causes nonlinear thermal absorption, leading to stress concentration and cracking. 1. Where Do...
- What factors determine the shape of an optical window? 7/7/2026 1. Direct Conclusion Circular windows are more widely used in optical systems. This preference is not driven by optical performance—both circular and rectangular windows can achieve essentially identical transmitted beam quality—but rather by the fact that circular windows offer lower overall cost and more mature processing techniques across four key aspects: fabrication, inspection, sealing, a...
- Impact of Coloration Phenomena in Optical Glass on Optical Component Performance and Mitigation Strategies 6/30/2026 The functional core of optical components lies in the precise manipulation of light waves, with the material's transmittance and spectral characteristics serving as the foundation for system performance. Under prolonged use or specific operating conditions, the discoloration of optical glass—typically manifesting as yellowing or reduced transmittance—directly degrades imaging quality and energy tr...
- Why does a fused silica ring need to be "drilled"? 6/23/2026 In the semiconductor, fiber optic communications, and aerospace industries, there is a seemingly unremarkable component—the fused silica ring. It doesn't "show off" like a lens, nor does it alter optical paths like a prism. Yet without it, lithography machines could not focus precisely, fiber optic signals might suffer attenuation, and even spacecraft attitude control systems could fail. Today,...
- From Gaussian to Ring Beam: The 170°Conical Aluminum Mirror Solution 6/17/2026 In laser processing, LiDAR, optical measurement, and related fields, transforming a standard circular Gaussian beam into a uniformly distributed ring-shaped beam is a classic and important engineering challenge. Conventional approaches often rely on axicons, diffractive optical elements, or spatial light modulators, but these solutions suffer from high cost, sensitivity to alignment, and limited d...
- With the explosive growth of AI optical interconnection, why has BK7 glass become a "necessary accessory"? 6/9/2026 As the parameters of large AI models exceed trillions, data transmission rates within data centers are rapidly increasing from 56Gbps to 112Gbps and even 224Gbps. In this computing power race, a seemingly traditional material—BK7 glass—is making a strong comeback as a "necessary component" at the core of the industry chain. I. Why is glass indispensable for AI optical interconnection? ...
- The “Polarization Scam”: When a Laser Hits Your Mirror at an Angle 6/2/2026 I.A common 'train wreck' scenario You bought a reflector from a supplier; the specifications state a reflectivity of 99.9%. You install it in the optical path, shine a laser on it, and the actual reflectivity is only 96%. Your first reaction: the supplier misrepresented the specifications. The supplier sends a factory inspection report: the testing conditions were correct, and the actual ref...
- Performance Specifications for Narrow Bandpass Filters Under Standardized Calibration 5/26/2026 I. Product Specifications for Narrow Bandpass Filters Narrow Bandpass Filters are designed to precisely transmit light within a specified, extremely narrow wavelength band while effectively blocking all other wavelengths.

- Precision Aspherical Lens Fabrication Technology and its Optical Application Value 5/20/2026 Compared to spherical lenses, aspherical lenses have a continuously and gradually changing curvature, which can correct various aberrations such as spherical aberration and coma at their source. They have the characteristics of single-lens replacement of multiple lenses, superior imaging quality, high light energy utilization, and lightweight system. They are widely applicable to high-end scenario...
- High-power laser window, why does fused silica completely outperform BK7? 5/12/2026 In high-power industrial laser equipment such as laser cutting machines and laser welding machines, the laser protection window is the core barrier protecting the optical system. Many customers wonder: why is fused silica chosen for high-power applications, while BK7 glass is only suitable for low-power conditions, even though both are commonly used optical materials? Zoolied will provide an in-de...
- Differences in the Optical Properties and Applications of Plano-Convex Lenses and Positive Meniscus Lenses 5/6/2026 In optical system design, plano-convex lenses and positive meniscus lenses are both core converging elements, widely used in imaging, laser focusing, and optical path calibration. Although both are positive lenses (positive focal length, converging light rays), they differ fundamentally in structural configuration, optical parameters, aberration characteristics, and applicable scenarios, directly ...
