- Comparison of BK7 Ball Lens and half Ball Lens Technologies 4/8/2026 Both BK7 Ball Lens and half Ball Lens are manufactured from optical-grade BK7 borosilicate glass, which is precision-ground and polished to shape; they serve as core components for controlling light paths in micro-optical systems. Although both rely on the same high-quality substrate and offer high light transmittance, excellent physical and chemical stability, and good machinability, they differ ...
- Automotive optics upgrade: starting with a single lens 4/1/2026 Driven by the twin forces of electrification and intelligentisation, the automobile is evolving from a traditional mode of transport into an ‘intelligent mobility space’. As a key enabler of autonomous driving perception, human-vehicle interaction and the in-cabin experience, automotive optics has become a core area of technological innovation within the automotive industry. Based on optical compo...
- Sapphire: the ‘transparent armour’ of the optical world 3/26/2026 When sapphire is mentioned, most people think of that deep blue hue found in jewellery. However, in the eyes of materials scientists, the true value of this single crystal of α-alumina (chemical formula Al₂O₃) lies in its ‘hardcore’ optical properties—its physical characteristics, including a Mohs hardness of 9 (second only to diamond), enable it to withstand abrasion from sand and dust; a broad ...
- The Key Considerations for Selecting Optical Dome 3/19/2026 As a core protective component in optical detection and imaging systems, optical domes combine light transmission, sealing, and pressure resistance. When selecting a dome, it is essential to consider optical performance, mechanical strength, environmental compatibility, and installation precision to avoid imaging distortion, light transmission loss, or structural failure caused by parameter mism...
- Why are the Fused Silica windows so popular? 2/28/2026 In today's era of rapid optical technology advancement, Fused Silica windows are ubiquitous in nearly all precision optical systems—from deep ultraviolet lithography machines to high-power laser cutting equipment, and from aerospace remote sensing systems to biomedical detection instruments.
