Mid-IR waveplate Middle Infrared Zero Order/IRW series

zero order

Middle Infrared zero order waveplate is constructed by two Magnesium Fluoride (MgF2) plates with their fast axis crossed, the two plates are constructed by optically contacted method, the optical path is epoxy free. The difference in thickness between the two plates determines the retardance. Middle Infrared zero order waveplates is widely used in infrared applications, ideally for 2.5-6.0 micron range. Ideal for Applications in the 2.5-6.0μm Range High Damage Threshold Better Temperature Bandwidth Wide Wavelength Bandwidth Both Sides AR Coated RoHS Compliant Specifications: Material MgF2 Dimension Tolerance +0.0/-0.2mm Wavefront Distortion <λ/4@632.8nm Retardation Tolerance <λ/100 Parallelism(single plate) 90% central area Standard Wave quarter-wave(λ/4), half-wave(λ/2) Wavelength Range 2500-6000nm Damage Threshold >1J/cm2, 20ns, 20Hz @1064nm AR Coating R<1%@central wavelength
