Description
Photonchina offers an exceptional range of cylindrical lenses, designed to focus light onto a line rather than a point, distinguishing them from traditional spherical lenses. These lenses feature curved surfaces that are sections of a cylinder, allowing them to compress images in one direction while maintaining their original form in the perpendicular direction. This unique characteristic makes Photonchina's cylindrical lenses ideal for applications requiring precise control over light directionality and image shaping.
Photonchina's cylindrical lenses are renowned for their superior surface quality, dimensional accuracy, and irregularity control. These lenses are crafted to meet high precision standards, accommodating special shapes and specifications as per customer requirements. The meticulous attention to detail in manufacturing ensures that each lens delivers optimal performance, making them a preferred choice for correcting diode laser outputs and enhancing optical systems.
Photonchina provides a general overview of the soft limits in lens fabrication. As designs approach these limits, the complexity of manufacturing increases, potentially incurring additional costs for specialized fixturing. Despite these challenges, Photonchina excels in producing lenses with exceptional aperture coverage and dimensional accuracy, ensuring that each product meets stringent quality standards.
Commitment to Quality is evident in Photonchina's capabilities, which surpass standard and premium levels in several key attributes. With tight tolerances on diameter, central thickness, and radius, along with outstanding surface quality and irregularity control, Photonchina's lenses are engineered to deliver unparalleled performance. Their dedication to precision and quality assurance makes Photonchina a leader in the optical lens industry.

Frequently Asked Questions
A cylindrical lens is an optical lens that focuses light onto a line instead of a point, compressing the image in the direction perpendicular to the line and leaving it unaltered in the direction parallel to it.
Photonchina's cylindrical lens has top-level surface quality, irregularity, and dimension tolerance. It also provides high precision, special shapes, and specifications designed by customers.
Cylindrical lenses are used to correct the output from diode lasers, to produce a round beam from the diode's elliptical output. They are also applied in optical systems to correct the shape of laser beams, change image aspect ratios, and illuminate in the shape of a line source.
The manufacturing limits for Photonchina are represented by a general list of soft limits and are intended for reference only. As requirements move closer to a min or max shown, fabrication becomes more difficult. Certain combinations are attainable, with extra significant fixturing costs, e.g. crossed axis cylinders, cylinders/spheres. Aperture coverage is often limited by the range of diffractive nulls available.
Photonchina's cylindrical lens has a diameter tolerance of +/-0.100 mm, central thickness tolerance of +/-0.150 mm, and radius tolerance of +/-1.0%. It also has surface quality of 60-40, irregularity of 1/4 Lambda, and centration of +/-8 arc min.
