Middle Infrared Zero Order Waveplate

Description

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
