Crystal wavelength plates (phase difference plates) usable for various applications. Available in multi-order and zero-order!
Crystal wavelength plates (phase plates) featuring multi-order and zero-order options are suitable for various applications. Multi-order wavelength plates are ideal for applications where the actual operating wavelength falls within ±1% of the design wavelength of the plate. For applications that do not fall within ±1%, zero-order wavelength plates, which have low wavelength and temperature dependence, are recommended. To facilitate system integration, the gold frame is marked with a fast axis. ■ Zero-order and multi-order types ■ λ/4 and λ/2 retardation ■ Fixed in a gold frame with black anodized finish ■ Zero-order polymer wavelength plates are also available *You can download the catalog from Edmund Optics Japan below.

Multi-order wave plates are suitable for use with monochromatic light that oscillates within 1% of the design wavelength. Zero-order wave plates achieve high performance over a broader range of wavelengths and temperatures. Achromatic wave plates provide consistent performance over a wide range of wavelengths and temperatures. For more details, please visit the official Edmund Optics website via the link below.
Laminating resin films with birefringent properties! They are bonded between substrates with excellent optical characteristics.
The "SB-RETAX" is a wavelength plate that, when linear polarized light is incident, provides a continuous and constant phase difference over a wide wavelength range. It is constructed by laminating a resin film with birefringent properties between substrates with excellent optical characteristics. Depending on the wavelength range in which the effect is obtained, there are differences in the number of film layers, available in two types: 3 layers and 5 layers. 【Features】 ■ Provides a continuous and constant phase difference over a wide wavelength range ■ Custom products - In addition to standard products, we can consider specifications such as substrate material, shape, size, and thickness according to your requirements - Since it uses resin film, it can accommodate larger sizes of Φ30 or more - Even if the wavelength range is changed, production is possible starting from the optical design of the film *For more details, please refer to the PDF document or feel free to contact us.
A crystal wavelength plate is a wavelength plate made by optically contacting two birefringent plates of different thicknesses so that their optical axes are perpendicular to each other.
We provide integrated in-house processing from crystal cutting to shaping, polishing, anti-reflective coating, and optical contact, utilizing advanced crystal processing technology represented by high-precision polishing at Optical Research Institute. We also support design and phase difference evaluation, so please feel free to inquire about custom specifications and development products.
The highest quality aimed at the latest technology.
We design and manufacture wave plates (phase plates) for each wavelength. We offer single-layer types and laminated types (optical contact or adhesive bonding).
Crystal wavelength plates for projectors can also be produced! We offer 1/4 wavelength plates and 1/2 wavelength plates.
The "crystal wavelength plate" is an optical element that utilizes the birefringence of crystal to create a phase difference in light, enabling circular and linear polarization. It is used in optical pickups for DVDs, reading devices such as digital copiers, and optical communications. Additionally, crystal wavelength plates for projectors can also be manufactured. 【Features】 ■ Optical element for circular and linear polarization ■ Crystal wavelength plates for projectors can also be manufactured ■ Usable in reading devices such as optical pickups for DVDs and optical communications *For more details, please refer to the PDF document or feel free to contact us.
Zero-order wave plates with enhanced transmittance due to AR coating treatment on both sides. A rich lineup of wavelengths is available for λ/2 plates and λ/4 plates.
This is a wavelength plate made from two thin slices. It is used to introduce a phase difference between two orthogonal polarization components and to change the state of incident polarized light. There are λ/2 plates and λ/4 plates; the λ/2 plate shifts the phase difference by λ/2 (180°) and rotates the incident linear polarization. The λ/4 plate shifts the phase difference by λ/4 (90°) and is used to convert linear polarization into circular polarization. To maximize transmission, a multilayer dielectric anti-reflection coating is applied to both sides of the wavelength plate. The wavelength plate is delivered mounted. - Easy adjustment - Wide temperature tolerance - Wide wavelength bandwidth - Compatible wavelength: 244 to 1550 nm - Suitable for both high-power and low-power lasers
