Photonics Advancement: from Chirped Mirrors, Super Achromatic Waveplates, to CLBO crystals

Shalom EO presents advanced laser optics at ICLO 2026, including chirped mirrors, super achromatic waveplates, and CLBO crystals for UV and ultrafast 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.
