True Zero Order Λ/2 Half Wave Plate, Large Feild Angle, For Imaging Systems Overview: Comparing with normal two plates design Zero order waveplates having a relatively larger thickness which reduces the field angle, the True zero order wave plates are made of a very thin plate or cemented with a BK7 substrate, which ensures the best possible field angle, temperature and wavelength performance. True zero order waveplate is widely used in laser Lab and optical instrument. True

Optically Contacted Zero Order Λ/4 Quarter Wave Plate, Optical Path Glue-Free Overview: Optically contacted zero order waveplate is made from two multiple order plates with slightly different thicknesses. The two plates are constructed by optically contacted method and this design allows the optically contacted zero order waveplate to operate well in relatively high power application and wide wavelength range. The slow axis of one waveplate is aligned with the fast axis of

Multiple Order λ/4 Quarter Wave Plate, High Damage Threshold, Low Cost Overview: A Multiple Order Wave plate is made from a single birefrigent crystal (crystal quartz is the most commonly used material) that produces an integer multiple of the rated retardance. Quarter Wave Plate is one of the common types of waveplates which converts linearly polarized light into circularly polarized light or vice versa. While a multiple order waveplate produces an integer multiple of rated

Air Spaced Zero Order λ/2 Half Wave Plate, High Damage Threshold Overview: Air spaced zero order waveplate is built by placing a spacing ring between the two multi-order wave plates to form an air gab between them. The slow axis of one waveplate is aligned with the fast axis of the other waveplate. The slightly different thickness of the two multi order waveplates is chosen to achieve the required retardance. Air spaced zero order waveplate is designed for high damage

Achromatic Λ/4 Quarter Wave Plate, Wide Spectral Bandwidth For Tunable Lasers Overview: Achromatic Wave Plates (Retarders) are a pair of crystalline quartz and magnesium fluoride plates of controlled thickness with crossed fast axes to create a λ/2 or λ/4 delay in the broad wavelength range. Quarter wave plates can turn linearly polarized light into circularly polarized light and vice versa. The difference in dispersion between materials allows the arrangement of a slow phase

Single Plate High Power Quartz Waveplate, High Energy, Wide Acceptance Angle Overview: Single Plate High Power Quartz Wavep lates are available in both λ/4 and λ/2 retardance for discrete laser wavelengths from the UV to NIR and can withstand energy densities up to >10 J/cm2 at 1064nm. A large acceptance angle and wide operating temperature range enables these waveplates to be integrated into harsh environments applications. The extremely thin thickness which can be made down

Optically Contacted Zero Order Λ/2 Half Wave Plate, Optical Path Glue-Free Overview: Optically contacted zero order wave plate is made from two multiple order plates with slightly different thicknesses. The two plates are constructed by optically contacted method and this design allows the optically contacted zero order waveplate to operate well in relatively high power application and wide wavelength range. Optically contacted zero order waveplates also feature particularly

Air Spaced Zero Order λ/4 Quarter Wave Plate, High Damage Threshold Overview: Air spaced zero order wave plate is built by placing a spacing ring between the two multi-order wave plates to form an air gab between them. The slow axis of one waveplate is aligned with the fast axis of the other waveplate. To achieve the required retardace will request carefully match the thickness differences of the two multi order waveplates. For high power lasers and applications require to

Dual Wavelength Waveplate, Dual-wavelength Light Source, SHG Lasers Overview: Dual Wavelength Wave plate is designed to simultaneously meet specific retardation at two individual wavelengths in applications for dual-wavelength light source according to the fitting of the refractive index at different wavelengths. Dual Wavelength Waveplates are particularly useful when used in conjunction with other polarization-sensitive components to separate coaxial laser beams of different
