Infrared Glass Window
Infrared-transmitting optical glass includes oxide and nonoxide/chalcogenide glass. Oxide glasses generally serve visible, near-infrared, and short-wave infrared, with only a few suitable for mid-wave infrared. Chalcogenides serve short-, mid-, and long-wave infrared. When conventional IR materials reach their limits, infrared glass (IRG) supports demanding applications through cost, performance, and processability. These glasses cover common 3-5 micrometer and 8-12 micrometer bands and can transmit down to 0.7 micrometers. Infrared-transmitting glass serves infrared detection and imaging. Special physical/chemical properties permit transmission of infrared radiation, defined here as electromagnetic wavelengths from 760nm to 1000um. Near-, mid-, and far-infrared transmit to differing degrees. Used as windows, lenses, and other critical optics, the glass guides target-emitted energy along specified paths for detection, thermometry, imaging, and recognition. Transmission and refractive index are important selection factors, closely related to material structure, lattice vibrations, and electronic absorption. Different materials/structures can have substantially different transmission in the same band, so select for the application. Broad applications include military, security, firefighting, vehicles, and epidemic prevention. Demand grows with infrared technology, especially low-cost uncooled detectors. The global infrared-glass market is expected to continue growing over coming years, supporting infrared technology development. Transmission curve: 10mm thickness.

Astro-Sital CM Series Ultralow-Expansion Glass-Ceramic Optical Material Oeengine
mean linear coefficient of thermal expansion (CTE) within temperature range -60 to 60 °C: 0±1.5 10⁻⁷ °C⁻¹ CTE homogeneity: <= 0.2 10⁻⁷ °C⁻¹ specific heat capacity: 0.22 kilocalorie kg⁻¹ °C⁻¹
Many optical applications require a substrate material with a near-zero coefficient of thermal expansion and/or excellent thermal shock resistance. Astrosital, equivalent to Zerodur™ (registered trademark of Schott Glass Technologies) is a glass-ceramic material with ultra low thermal expansion. Astronomical and x-ray telescope mirrors are prime examples of application. Another well known application is production of mirror substrates for microlithography. Maximum available size: 2,000 mm Dia (or 1,000 mm Square) x 300 mm thick.

A microlens array (MLA) is a high-precision optical component composed of hundreds or thousands of tiny, uniformly arranged micro lenses on a single flat substrate. Unlike traditional single lenses that focus one light beam, a microlens array can split, homogenize, and reshape light on a micro scale. It is widely paired with VCSELs, lasers, and image sensors, becoming a core part of modern miniature optical systems.
A laser bar is an array semiconductor laser chip integrated with dozens of emitters, which realizes hundred-watt quasi-continuous output on a single chip. With regular emitter arrangement and controllable fill factor, integrated thermal design and superior wall-plug efficiency compared to single chips, it acts as the core light source for high-power pumping, medical lasers and precision processing.
