Selection Tutorial for Lens Assemblies
This is a basic tutorial and guide to help you understand some important glossaries when you are selecting Optical Lenses and Camera Lenses.
Harmonic Generation
This article explained what is harmonic generation (or frequency conversion), which is the result of the utilization of nonlinear optical effects, and other contents including type I, type II phase matching.
Categories of Optical Crystalline Birefringence Polarizers
An Optical Polarizer is an optical element that screens light and split it into two beams with a specific ratio according to its polarization state. This article unfolds a basic concept and working principles of different categories of birefringent crystal polarizers including Glan polarizers (Glan Thompson, Glan Taylor), Wollaston Polarizers, and Rochon Polarizers. In the text, we also introduced two kinds of optical parts related to polarization: Polarization Rotator and Depolarizer.
BBO Crystals and Its Applications
This article describes the applications of BBO Crystals (beta barium borate crystals), including Optical Nonlinear Frequency Conversion (Harmonic Generation and OPA, OPO), Electro-optical Modulations (EOM), and Spontaneous Parametric Down Conversion (SPDC).
BBO Crystals Supporting the Research of Quantum Entanglements
This article describes the intricacies of quantum entanglements, the application of Bell inequalities, and the crucial role played by Beta Barium Borate (BBO) crystals in the phenomenon of Spontaneous Parametric Down-Conversion (SPDC).
KTA Crystals for Optical Parametric Oscillation
In this article, we discuss the distinctive features of KTA crystals, their application in optical parametric oscillation, and a comparative analysis with Potassium Titanyl Phosphate (KTP) crystals.
Optical Basics: The Nature of Light and Optical Elements
This article aims to provide a comprehensive understanding of essential Optical Basics, ranging from the nature of light (including wavelength, the electromagnetic spectrum, phase and amplitude, the wave-particle duality of light, to reflection, refraction, birefringence, and interference) to the operation principle of optical elements.
Nd:YVO4
Nd:YVO4 is an important material in laser technology. Nd: YVO4 refers to neodymium (Nd) doped into yttrium orthovanadate (YVO4) crystal, forming a composite material with excellent optical properties. This material is widely used in laser technology, particularly in solid-state lasers.
Understanding Optical Specifications-Geometric Specifications
A guide that helps understand the glossaries of optical specifications including thickness diameter tolerance, angle tolerance, center error, radius of curvature, clear aperture, parallelism, etc.
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.
