Features

• By combining two crystals with different wavelength characteristics of the phase difference, we achieved a zero-order waveplate with a small change in phase difference over a wide wavelength range.
• Beca*** of the air gap type, it can also be ***d for high-power lasers.
• Since it is a zero-order waveplate, the change in phase difference due to temperature change is small and very stable.
• There are two types of wave plates: a 1/2 wave plate that can rotate the polarization direction and a 1/4 wave plate that can convert linearly polarized light into circularly polarized light.
• A total of four types are available: three infrared types with different bands and visibility types.
• The optical element is fixed to the frame so that stress is not applied to the element when it is held in the holder.
• Both sides of the two elements (four in total) are coated with anti-reflection coating, resulting in high transmittance.
• A Fresnel Rom Wavelength Plate (FRB) is also available.
• * Before ***, make sure that the energy density of the incident laser beam does not exceed the laser capacity.
• * The thickness of the frame (6 mm) may vary dep***ing on the device specifications.
• * When using a high-energy pulsed laser, *** an air-gap type wave plate (WPQG).
• * Do not touch the screws on the waveplate frame.
• * The characteristics may deteriorate or the device may fall off.
• * If a strong impact is applied to the waveplate frame, the axis of the element may become misaligned.
