Choosing between an F1.0 Blacklight lens and traditional IR illumination for night FPV flights is a battle of fundamental physics. We break down the real-world trade-offs in MTF, thermal drift, and color data.

On New Year’s Day 2026, the team from Shanghai Silk Optical Technology Co., Ltd. journeyed to the revolutionary heartland of Jinggangshan. On this historic soil, they embarked on a journey designed for both spiritual enrichment and team cohesion. Centered on the "Jinggangshan Spirit," the event served as a bridge to strengthen unity, tempering the corporate spirit through a look back at history and injecting powerful momentum into the company’s mission for the coming year.

The special effect of polarizer is to effectively exclude and filter the scattered light in the beam. The light can be put into the eye visual image in the right light axis, so that the visual field is clear and natural. Like the principle of blinds, light is adjusted to the same direction of light into the room, nature makes the scene look soft and not harsh.

For procurement managers and hardware engineers planning their Q3 and Q4 production runs, the optical components supply chain is currently flashing a warning sign. While the cost of standard silica sand remains relatively stable, the specialized raw materials required for advanced machine vision and high-definition security lenses are experiencing distinct upward pressure. The culprit is not standard glass, but High-Refractive-Index (HRI) glass. As the industry demands larger apertures (F1.0) and higher resolutions (5MP to 8MP), the reliance on specialized HRI glass has skyrocketed. However, recent market data from Q1 and Q2 of 2026 indicates that the raw materials required to produce this glass are facing supply tightening and price volatility.
