Corning Eagle XG
Corning Eagle XG is a synthetic Alkaline Earth Boro-aluminosilicate glass designed for Liquid Crystal Display (LCD) and other electro-optical applications. Eagle XG glass features low density, 92% transmission in the visible spectrum, an extremely smooth surface, and impressive strength to allow thinner and larger dimensions. The glass also has the advantage of a high resistance to weathering (the erosion induced by gases and vapors in the atmosphere). The data sheets and properties of Corning Eagle XG are shown below.
How to Clean Your Optics
Knowing how to correctly clean your optics is extremely crucial. For different kinds of optics (e.g. Bare Metallic Substrates, Coated Optics, Flat and Spherical Lenses, etc.) different treatments are needed, cleaning optics without guidance could damage or even devastate the optics. Shalom EO introduces proper approaches for cleaning optics in this article.
Double Surface Super-Polishing Technique
Hangzhou Shalom EO has successfully developed a double surface polishing method for processing high precision optical windows or substrates, made from N-BK7 and UV Fused Silica, which are one of the most crucial components for Femto-line laser systems.
Super Polished Substrates or Mirrors
Hangzhou Shalom EO has successfully evolved the classical super-polishing technique, the technique developed by Shalom EO could ensure roughness less than 1Å of the optics while accommodating volume quantity production.
Introduction to Acousto-Optic Crystals
Acousto-Optic Crystals are crystals that exhibits photoelastic effects, where mechanical waves stimulate elastic strains in the crystals, acting as periodic phase gratings and alters the refractive indices, leading to changes in the optical properties. The AO crystals are excellent candidates for to be processed into the acouto-optic medium of the Acousto-Optic Modulators (AOM) including AO Q-switch, Acousto-Optic Deflectors (AOD), Acousto-Optic Frequency Shifter (AOFS), and Acousto-Optic Tunable Filters (AOTF), etc.
SCHOTT ZERODUR
SCHOTT ZERODUR is a lithium aluminum silicon oxide glass-ceramic of zero porosity. Glass Ceramics are manufactured from controlled crystallization and nucleation of glass substrates, resulting in its mixed inherent properties of both glass and ceramic. Among them, SCHOTT ZERODURis iconic for its near-zero coefficients of thermal expansion (CTE), which is a result of its counterbalancing microscopic system and the glass matrix.
BOROFLOAT33
BOROFLOAT33 is a SCHOTT designation of borosilicate glass made by a unique microfloat technology. Its excellent thermal, mechanical, chemical and optical properties yielded versatility and stature in multitudes of applications.

Super Achromatic Waveplates
Shalom EO recently joined the development of Super Achromatic Waveplates. Unlike conventional achromatic waveplates, super achromatic waveplates consist of six waveplates aligned together, three made from quartz (Crystalline SiO2) and three made from magnesium fluoride (MgF2). With an increased number of composing waveplates, this design minimizes the fluctuations of retardation and substantially broadens the application spectrum from the UV to the NIR.
JGS1
JGS1 is a synthetic UV-grade quartz glass suitable for optical applications equivalent to Corning 7980. JGS1 has high transmission across the UV to the NIR spectrum (180-2500nm), and is particularly advantageous for application in the UV range. However, like most UV grade Fused Silica, JGS1 contains relatively higher OH compositions than the IR grade Fused Silica, which leads to higher absorption in the IR band.
