Hot New Products Infrared Crystals - Fresnel Rhomb Retarders – Dien

Fresnel Rhomb Retarders like broadband waveplates providing uniform λ/4 or λ/2 retardance over a wider range of wavelengths than possible with birefringent waveplates. They can replace retardation plates for broadband, multi-line or tunable laser sources. The rhomb is designed so that a 45° phase shift occurs at each internal reflection creating a total retardance of λ/4. Because the phase shift is a function of the slowly varying rhomb dispersion, the retardance change with wavelength is mu...

OEM Manufacturer Large Nonlinear Coefficients Zgp Crystal - GaSe Crystal – Dien

Gallium Selenide (GaSe) non-linear optical single crystal, combining a large non-linear coefficient, a high damage threshold and a wide transparency range. It is a is very suitable material for SHG in the mid-IR. The frequency-doubling properties of GaSe were studied in the wavelength range between 6.0 µm and 12.0 µm. GaSe has been successfully used for efficient SHG of CO2 laser (up to 9% conversion); for SHG of pulsed CO, CO2 and chemical DF-laser (l = 2.36 µm) radiation; upconversion of CO...
High Performance Optical Crystal - Zero-Order Waveplates – Dien

The zero order waveplate is designed to give a retardance of zero full waves, plus the desired fraction.Zero order waveplate shows better performance than multiple order wavepalte.It has broad bandwidth and a lower sensitivity to temperature and wavelength changes.It should be considered for more critical applications.
2021 China New Design Fs Crystal - Glan Thompson Polarizer – Dien

Glan-Thompson polarizers consist of two cemented prisms made from the highest optical grade of calcite or a-BBO crystal. Unpolarized light enters the polarizer and is split at the interface between the two crystals. The ordinary rays are reflected at each interface, causing them to be scattered and partially absorbed by the polarizer housing. The extraordinary rays pass straight through the polarizer, providing a polarized output. Feature： Broadband low power polarizers for UV, visible or ne...
Chinese Professional Yb Yag - Rochon Polarizer – Dien

Rochon Prisms split an arbitrarily polarized input beam into two orthogonally polarized output beams. The ordinary ray remains on the same optical axis as the input beam, while the extraordinary ray deviates by an angle, which depends on the wavelength of the light and the material of the prism (see the Beam Deviation graphs in the table to the right). The output beams have a high polarization extinction ratio of >10 000:1 for the MgF2 prism and >100 000:1 for the a-BBO prism. Feature：...
