Request InfoThorlabs Inc.NEWTON, N.J., Sept. 18, 2012 — Thorlabs has released its new line of achromatic wave plates for the 260- to 410-nm range. Achromatic wave plates are constructed from at least two birefringent materials, typically quartz and MgF2. To manufacture them for use into the UV, the company used a compound plate design of quartz and sapphire, resulting in a wider field of view than that produced by other materials because sapphire is a negative uniaxial crystal. And, because sapphire is a much harder material than MgF2, the quartz-sapphire wave plates are more durable and more resistant to scratching.See full productRelated content from Photonics MediaPRODUCTSPhotonics Spectra February 2023 IssueHolographic Grating SpectrometerThe HG10 Holographic Grating Spectrometer from Thorlabs Inc. is a fiber-based, high-speed device that provides sub-nm resolution in the 810- to 965-nm optical range.
