Best Price on Q-Switched Material - Achromatic Waveplates – Dien

Achromatic waveplates by using two pieces of plates.It is similar to Zero-order waveplate except that the two plates are made from different materials,such as crystal quartz and magnesium fluoride. Since the dispersion of the birefringence can be different for the two materials,it is possible to specify the retardation values at a wavelength range. Features: Spectrally Flat Retardance Operating Ranges from UV to Beyond Telecom Wavelengths AR Coatings for: 260 – 410 nm, 400 – 800 nm, 690...
Short Lead Time for Infrared Material - Super Achromatic Waveplates – Dien

Super Achromatic Waveplate can provides extremely flat phase delay in a large Wavelength broadband. The broadband of Quarter Waveplates are 325-1100nm or 600-2700nm, the Half Waveplates are 310-1100nm or 600-2700nm. The Super Achromatic Waveplate of standard adopt Glued strutures.We can customize phase retardation and wavelength according to customer’s requirment. Features： •Provide flat phase retardation in a large spectral range. Quarter wave plate,used for 325-1100nm or 600-2700nm Half wa...
Best Price on Y3al5o12:Yb - 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...
Renewable Design for Kd P Eo Q-Switch - AGGS(AgGaGeS4) Crystals – Dien

The AgGaGeS4 crystal is one of the solid solution crystal with extremely tremendous potential among the increasingly developed new nonlinear crystals. It inherits a high nonlinear optical coefficient(d31=15pm/V), a wide transmission range(0.5-11.5um) and low absorption coefficient(0.05cm-1 at 1064nm). Such excellent properties are of enormous benefit to frequency-shifting near-infrared 1.064um Nd:YAG laser into the Mid-infreard wavwlengths of 4-11um. Besides, it has a better performance than...
Wholesale Dealers of Eye-Safe Q Switchs - Si Windows – Dien

ZnS is a very important optical crystals applied in IR waveband. Transmitting range of CVD ZnS is 8um-14um, high transmittance, low absorption, ZnS with multi-spectrum level by heating etc. static pressure technics has improved the transmittance of IR and visible range. Zinc Sulphide is produced by synthesis from Zinc vapour and H2S gas, forming as sheets on Graphite susceptors. Zinc Sulphide is microcrystalline in structure, the grain size being controlled to produce maximum strength. Multis...
Best-Selling Nlo 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.
