4μm λ/4 MWIR Zero Order Waveplate

Product Details Ideal for Applications in the 3 – 7μm Range λ/4 and λ/2 Retardance Mounted for Easy Alignment and System Integration Our zero order Mid-Wave Infrared (MWIR) Waveplates are designed for applications in the 3 – 7μm wavelength range. When compared to multiple order waveplates, zero order waveplates provide increased bandwidth and lower sensitivity to temperature change. These waveplates are available with λ/4 or λ/2 retardance in a range of wavelengths, offer efficient retardation over broad spectral ranges, and are ideal for a variety of infrared (IR) applications. Each MWIR waveplate is anti-reflection coated, and has been mounted to ease system integration.
