An Optically Contacted Zero Order Wave plate refers to a specific type of wave plate that achieves zero-order performance through direct optical contact between two plates. This design eliminates the need for cement or adhesive layers typically used in wave plate construction.
Utilizing the double wave plates structure, a Zero Order Wave plate effectively offsets the unfavorable sensibility of retardation, since the disturbing retardation shifts in the first plate will be compensated after light emerges from the second plate, thus making Zero Order Wave plates substantially far less sensitive to changes in temperature and wavelength than their multi-order counterparts. However, changes in the angle of incidence will still affect the phase delay.
CRYSMIT' Optcially Contacted Zero Order Wave plates are made from Quartz (suitable for the wavelength range 200-2000nm).
These wave plates are commonly used in applications where precise wavefront manipulation, minimal wavefront distortion, and high optical quality are required. They find applications in areas such as optics, laser systems, interferometry, spectroscopy, and polarization control.
It is important to note that proper handling and cleaning procedures should be followed to maintain the optical contact and avoid damage to the wave plates' surfaces.
6 advantages of Optically Contacted Zero Order wave plate
Improved Optical Performance: The direct optical contact between the wave plate components ensures precise alignment and eliminates the use of adhesives or cement layers that can introduce optical distortions or wavelength dependencies. This results in improved wavefront quality, minimal wavefront distortion, and enhanced optical performance.
Enhanced Stability: The absence of adhesive layers or cement reduces the risk of degradation or delamination over time. Optically Contacted Zero Order Wave plates maintain their performance and stability for a longer duration, making them ideal for applications that require long-term reliability.
Wide Wavelength Range: Optically Contacted Zero Order Wave plates can be designed to operate over a wide wavelength range, offering flexibility in various applications where multiple wavelengths are involved. They provide consistent performance and retardation values across the specified wavelength range.
Reduced Beam Deviation: With precise alignment and direct contact, Optically Contacted Zero Order Wave plates minimize beam deviation, maintaining the original beam's spatial quality and allowing for precise wavefront control.
Wide temperature bandwidth: it maintains its performance and retardation characteristics over a broad range of temperatures.
Enhanced Durability: The direct optical contact between the wave plate components provides better mechanical stability, ensuring durability and resistance to environmental factors such as temperature and humidity changes.
These advantages make Optically Contacted Zero Order Wave plates well-suited for applications that require high-precision wavefront manipulation, minimal distortion, broad wavelength coverage, and long-term stability. They are commonly used in fields such as optics, laser systems, interferometry, spectroscopy, and polarization control.
