Understanding Optical Specifications: Surface Specifications
This article offers a simple but thorough explanation of surface specifications, which is an essential subset of optical specifications and which include Surface Quality, Surface Flatness, Surface Roughness, Power, Irregularity, and Fracture/Chip. This knowledge will help you navigate the complexities of optics terms and enhance your grasp of optics concepts.
Understanding Optical Material Properties
In this article introducing optical properties, we will be discussing learning several important glossaries of optical material properties including: Refractive Index, Chromatic Dispersion, Optical Transmission, Absorption and Light Scattering, Optical Homogeneity, Laser Induced Damage Threshold (LIDT). In the end section, we will also explore the main types of optical materials and their individual characteristics.
The Optical Transmission and Properties of Sapphire Windows
Sapphire Windows, often called Sapphire Glass Windows or Sapphire Optical Windows, made of single crystal synthetic sapphire (Al2O3), are becoming more and more indispensable in the exclusive fields of electro-optics due to their combination of superior optical, chemical, and mechanical properties. This article that Shalom EO presents concentrates on the optical transmission and the optical properties of sapphire windows, including the transmission wavelength range of sapphire, the transmission rate, the birefringence, and orientations. We have also analyzed the different growth methods and grades of sapphire crystals.
Laser Induced Damage Threshold Tutorial
Laser-Induced Damage Threshold, or LIDT is the highest fluence or power density of laser radiation incident upon the optical component before any unacceptable damage occurs. This article offers a basic tutorial and explanation of laser damage threshold, including the definition of LIDT. The test method of LIDT, laser-induced damage threshold for CW laser and pulsed laser, the calculation formula, the laser damage mechanisms, how to scale LIDT, the causes of laser damage, and high power laser optics/coatings.
The Orientations and Applications of Synthetic Sapphire Crystals
Synthetic sapphire is a synthetic single crystal form of aluminum oxide (Al2O3) that has excellent mechanical, optical, and chemical properties, making it suitable for demanding applications in industries like aerospace, semiconductors, and medicine. However, the molecular structure of sapphire is complex and anisotropic. This article introduces the typical orientations for sapphire and the suitable applications for each orientation.
All About CLBO (Cesium Lithium Borate) Crystals
This article offers a comprehensive introduction of CLBO crystals, including the properties, data sheets, advantages, applications of cesium lithium borate as an nonelinear crystal material. This article also contain a comparison of CLBO with other two common NLO crystals (BBO crystals and LBO crystals).
Explore 755nm Alexandrite Laser Optics
Alexandrite lasers are laser sources that adopt the alexandrite crystal as the laser gain medium, operating at a wavelength of 755nm, and are among the most versatile and effective laser systems available today. Their unique properties make them essential tools in both medical and aesthetic applications. In this article, we will explore the uses of Alexandrite lasers, compare them with diode lasers, and shed light on the optical components that ensure their optimal performance.
How ZnS and ZnSe Are Replacing Germanium (Ge) in IR Optics
Due to recent exporting rules, the price of germanium on the global market is surging, and the delivery is much longer than before. Zinc Sulfide (ZnS) and Zinc Selenide (ZnSe) are increasingly used as substitutes for Germanium (Ge) in infrared (IR) optics. This article offers a detailed comparison and explanation of how ZnS and ZnSe are replacing Ge as IR optics in their optical performance, thermal and mechanical properties, and costs.
Instant Guide-Important Specifications for Ultrafast Optics
Ultrafast lasers, also interchangeably called ultrashort lasers, are defined as pulsed lasers with a pulse width of picoseconds or less than 1 picosecond (1 ps = 1 × 10^-12 s). They have been applied and are showing promise in areas such as laser drilling/cutting and micromachining. In this blog, we break down the five critical parameters you should evaluate before purchasing ultrafast optics, such as mirrors, lenses, windows, or dispersion compensation elements. We give you guidance on the following specifications: 1. The Wavelength Range, 2.Dispersion, 3. Dispersion Compensation, 4. Average Power, Fluence, Peak Power, 5. Laser Induced Damage Threshold, 6.Angle of Incidence, 7. Polarization, 8. Surface Specification.
Lanthanum Aluminate (LaAlO3)
Lanthanum aluminate crystals, with the chemical formula LaAlO3 (LAO), belong to the hexagonal system and have a distorted perovskite structure. Lanthanum aluminate crystals have excellent mechanical strength, thermal stability, and chemical stability, and exhibit good lattice compatibility with a variety of functional oxide materials, such as high-temperature superconducting and ferroelectric thin films.
