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.

Important Specs for Infrared Thermal Imaging Camera Lenses

When it comes to purchasing the proper infrared (IR) thermal imaging camera lens for your specific usage, understanding the technical specifications is crucial to ensure that you acquire the lenses that suit your intentions. This article will cover concepts, definitions, and the Impacts of the Important Specifications for Infrared Thermal Imaging Camera Lenses including detector type, resolution, FOV, f-number, etc.

光学镀膜全面指南

光学镀膜是沉积在光学元件基底（如窗片、透镜、镜面）上的薄膜。通过控制反射、透射、吸收和散射，这些镀膜改变光与光学介质之间的相互作用，从而使光在各种应用中实现精确操控。

Quarter Wave Plates and Half Wave Plates

Wave plates, also known as retarders, are essential optical components made of birefringent materials that are designed to manipulate the polarization state of light. A waveplate alters the phase relationship between orthogonal components of polarized light, introducing a specific phase retardance. In this article, we will help you to understand quarter wave plates and half wave plates, how quarter waveplates and half waveplates change the polarization states, and explain the uses of quarter wavelength plates and half wavelength plates.

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.
