Germanium
Germanium is a chemical element located in group 14 of the periodic table, with the atomic symbol Ge. It is classified as a metalloid or semi-metal due to its unique properties, lying on the boundary between metals and non-metals. Key Properties and Applications of Germanium Physical Properties: Appearance: Germanium is a silver-white solid with a shiny, hard, and brittle texture. Melting Point: 938.4°C (1721.1°F) Boiling Point: 2830°C (5126°F) Thermal Conductivity: Germanium has high thermal conductivity, making it valuable in applications requiring efficient heat dissipation. Electrical Resistivity: The resistivity of germanium varies with temperature, which is fundamental to its role as a semiconductor material. Chemical Properties: Stability: Germanium is stable in air and water at room temperature but reacts with oxygen at high temperatures to form germanium dioxide (GeO₂). Reactivity: It…
Difference Between Industrial and Camera Lenses: What You Need to Know
Since our founding in 2010, we have been dedicated to the precision manufacturing of optical components. In 2018, we expanded our capabilities by establishing an R&D department focused on optical design, lens assembly, and the integration of opto-mechanical-electrical systems. As part of our commitment to sharing knowledge and supporting our clients, this article explores the key differences between industrial lenses and consumer camera lenses. Introduction Lenses are at the heart of all imaging systems, but not all lenses are created equal. While consumer camera lenses are designed for everyday photography, industrial lenses are engineered for high-performance imaging in rigorous environments. Understanding the difference between these two types of lenses is critical for selecting the right optical solution for your application. Key Differences between Photographic Lenses and Industrial Vision Lenses Here,…
Negative glass filter
A notch filter is an optical filter designed to block light at a specific wavelength or wavelength range while allowing other wavelengths to pass through. The main function of a notch filter is to “trap” a narrow band of the spectrum, effectively suppressing or filtering out light within that particular wavelength range. Notch filters are commonly used in applications that require precise removal of specific wavelengths of light, such as in laser systems, spectral analysis, and optical communication. Working Principle of Notch Filters The working principle of a notch filter relies primarily on interference effects or absorption mechanisms: Interference Effects: Multilayer Interference Coatings: Multiple layers of optical thin films are deposited on a substrate. The thickness and refractive indices of these films are precisely controlled to create interference effects that…
What Are Aspherical Lenses? Uses and Benefits Explained
What Are Aspheric Optical Elements? Aspheric optical components are lenses or mirrors with non-standard, non-spherical surfaces. Unlike traditional spherical optics, these elements feature customized freeform, elliptical, polygonal, or trapezoidal geometries that are tailored to meet specific optical performance requirements. They play a critical role in advanced optical systems across industries where high precision, compact design, or multifunctionality is required. Key Features of Aspheric and Irregular-Shaped Optics Custom Design Each component is uniquely engineered to minimize optical aberrations, improve imaging resolution, and optimize beam control. This results in compact, high-performance systems. Non-Standard Geometries These components go beyond circles and planes—featuring complex surfaces and edges that require ultra-precision fabrication. Multi-Functional Integration One optical element can integrate focusing, polarization, beam splitting, or wavefront control—functionality that typically requires multiple standard elements. High Efficiency By…
Acrylic filter
An acrylic filter is an optical filter made from acrylic material, also known as polymethyl methacrylate (PMMA). Acrylic is a lightweight, impact-resistant plastic with good optical properties and relatively low cost, making it widely used in the production of various optical components, including filters. Acrylic filters exhibit excellent optical characteristics and durability in many applications. Characteristics of Acrylic Filters Transparency: Acrylic materials have good transparency and can effectively transmit visible light and some near-infrared light. Impact Resistance: Acrylic is more resilient and less likely to break compared to glass, making acrylic filters more durable in practical applications. Lightweight: Acrylic is lighter than glass, so the filters made from it are also lighter, making them easier to handle and install. Machinability: Acrylic is easy to process and shape, allowing for the…
