Fuzhou Siaon Optoelectronic Technology Co., Ltd. provide Achromatic waveplate
Achromatic waveplate is similar to zero order waveplate except that the two plates are made from different birefringent crystals. Since the dispersion of the birefringence of two materials is different, it is possible to specify the retardation values at a broad wavelength range. So the retardation will be less sensitive to wavelength change. In other words, it can be used at a broadband wavelength range. Â

Fuzhou Siaon Optoelectronic Technology Co., Ltd.provides Cylindrical Lenses
Cylindrical Lenses are used in applications requiring magnification in one dimension only, such as in transforming a point image into a line image or changing the height of an image without changing its width.
Fuzhou Siaon Optoelectronic Technology Co., Ltd.provides Meniscus Lenses
Meniscus Lenses are manufactured with one convex surface and another concave surface. It can be a convergent lens or a divergent lens, which is decided together by refractive index, curvature and radius.
Fuzhou Siaon Optoelectronic Technology Co., Ltd.provides Beamsplitter plates
Beamsplitter plates can be used in high power laser system. The performance of beamsplitters is mainly dependent on the coating specifications.
Fuzhou Siaon Optoelectronic Technology Co., Ltd.provides BK7 Windows
BK7 window is the most common type of window, it has good performance over visible and near infrared wavelength region. The refractive index is 1.5168 at 587.6nm.
Glan Laser polarizer is made of two same birefringent material prisms that are assembled with an air space. Photonchinas polarizer is a modification of the Glan Taylor type and is designed to have less reflection loss at the prism junction. The polarizer with two escape windows allow the rejected beam to escape out of the polarizer, which makes it more desirable for high energy lasers. The surface quality of these faces is relatively poor as compared to that of entrance and exit faces. No scratch dig surface quality specifications are assigned to these faces.

Fuzhou Siaon Optoelectronic Technology Co., Ltd. provide Right Angle Prisms
Right angle prisms are used to deviate light by 90 degree or 180 degree. Depending on the orientation of the prisms, right angle prisms produce the inverted left handed image. Utilizing the character of critical angle, highly-efficient reflection inside is one of basic function of right angle prisms. Right angle prisms are easy to be mounted, have better stability and hardness for mechanical stress, are used in telescope and other optical system.
