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 Achromatic Lenses
The achromatic lens composes of two cemented elements , the kind of lens is designed to limit the effects of chromatic and spherical aberration.
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.
Fuzhou Siaon Optoelectronic Technology Co., Ltd.provides Glan Taylor Polarizers
Glan Taylor Polarizer is made of two same birefringent material prisms that are assembled with an air space. It has a length to aperture ratio less than 1.0 makes it a relatively thin polarizer. The polarizer with no side escape windows are suitable for low to medium power application where the side rejected beams are not required. The angular field of different materials of polarizers is listed below for comparison.
Fuzhou Siaon Optoelectronic Technology Co., Ltd.provides Glan Laser Polarizers
Glan Laser Polarizer is made of two same birefringence material prisms that are assembled with an air space. The polarizer with two escape windows allows the rejected beam to escape out of the polarizer which makes it suitable for high power laser.
Fuzhou Siaon Optoelectronic Technology Co., Ltd.provides Glan Thompson Polarizers
Glan Thompson Polarizer is made of two calcite prisms or two a-BBO prisms cemented together. Two types of Glan Thompsons are available. Glan Thompson polarizers tend to have higher extinction ratio than air spaced polarizers. a-BBO polarizers and Calcite polarizers can be used from about 220 to 900nm and 350 to 2300nm respectively.
Fuzhou Siaon Optoelectronic Technology Co., Ltd.provides Rochon Polarizers
Rochon Polarizer is one of the earliest designs, which is made of two birefringent material prisms cemented together. Both ordinary and extraordinary beams propagate collinearly down the optic axis in the first prism under the ordinary refractive index.

Glan Laser prism polarizer is made of two same birefringent material prisms that are assembled with an air space. The 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. The polarized field F1 and F2 of these is shown in the plot below.
Features:
Air-spaced
Close to Brewster's Angle Cutting
High Polarization Purity
Short Length
Suitable for low to medium power online_ordering where the rejected beam is not required
Mirror is a reflecting surface that forms an image of an object when light rays coming from that object fall upon it. Usually mirrors are made of plate glass, one side of which is coated with metal or some special preparation to serve as a reflecting surface.
UPT offers dielectric coated mirrors and metal coated mirrors which are made of substrate such as Bk7, K9, Fused Silica, CaF2, Sapphire.
