Description
Experience unparalleled precision and reliability with our expertly crafted quartz waveplates. Designed for advanced optical applications, these waveplates are meticulously manufactured to ensure exceptional performance. The use of high-quality quartz material ensures durability and stability, making them a preferred choice for professionals seeking excellence in optical components.
Our waveplates are engineered with a focus on minimizing imperfections, featuring a scratch and dig rating of 40/20~10/5. This ensures a pristine surface quality, essential for maintaining the integrity of transmitted light. Additionally, the transmitted wavefront distortion ranges from λ/2 to λ/8, providing superior optical clarity and precision.
Precision alignment is critical in optical systems, and our waveplates offer exceptional parallelism ranging from 3 arc seconds to 1 arc second. With a retardation tolerance of less than λ/300, these waveplates deliver highly accurate phase retardation, crucial for demanding applications. Furthermore, they are AR coated at a custom wavelength, enhancing their performance by reducing reflection losses.
Choosing the right waveplate involves several key parameters: wavelength, retardance type (such as half-wave or quarter-wave), and the order of the waveplate. Our selection includes various orders, with low order and several zero order options such as Cemented Zero Order, True Zero Order, Air Spaced Zero Order, and Optical Contacted Zero Order. Zero order waveplates offer broader wavelength, temperature, and angle bandwidths compared to low order waveplates.
Among the zero order types, True Zero Order and Air Spaced, as well as Optical Contacted types, boast a large damage threshold, making them suitable for high-power applications. However, True Zero and Optical Contacted types require more complex manufacturing processes. The Cemented type, while easier to produce, has a lower damage threshold, making it ideal for less demanding environments.

Frequently Asked Questions
A waveplate or retarder is an optical device that alters the polarization state of a light wave travelling through it.
Waveplates are constructed out of a birefringent material, such as quartz, for which the index of refraction is different for different orientations of light passing through it.
When you order the waveplates, you need to know the following important parameters: 1) What is the wavelength? 2) What is the retardance? Half waveplates or quarter waveplates or some special type? 3) What is the order?
Low order compared to zero order, zero order has more broad wavelength and temperature and angle bandwidth. For zero order, true zero order and air spaced and optical contacted type have large damage threshold. But true zero and optical contacted type are more difficult to produce. Cemented type has low damage threshold.
Waveplates have applications in laser optics.
