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 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 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.
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.
Hello, we offer a lot of 225,000 units of high quality sunglasses, coming from an optician. We have models for men, women and children. The shipment is immediate to any part of the world: Price: 1,5 euros per unit Minimum order: 5,000 units Conditions of sale: * This product must be sold outside Spain. * Price negotiation for the purchase of the whole lot.
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.
