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.

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.
