Product Description

Rod Lenses are polished on the circumference and ground on both ends. Optical performance is similar to a cylinder lens. Collimated light passing through the diameter of the rod lens will be focused into a line.
Fiber Optic Image Conduits transmit images from one polished face to the other and can be used straight or bent to fit space requirements without loss of light transmission.

Rod Lenses are highly polished small diameter rods made of optically transparent homogeneous materials. A carefully controlled manufacturing process produces rods (or fibers) with precise diameters and unsurpassed surface quality. Optical performance is similar to a cylinder lens. Collimated light passing through the diameter of the rod will be focused into a line.
 

Rod lens systems use special glass rods with optically finished ends, providing images with higher brightness, contrast and colour reproduction than conventional lenses. 

 

1. Cylindrical lens with its circumference surface polished.
2. Applicable for laser focusing into a line, changing beam shape into sheet-shape, or irradiating at a distance with elongated line
3. Focal length shortened by reducing the rod lense diameter compared to cylindrical lenses
4. Distortion-free, flexion-free, straight line gainable when projection was made at a distance, by precised process and polishing.
5. Suitable for collecting large sum of light into sensor by putting it right in front of line sensor.

VY Optics can make kinds of YAG crystals as per your request, such as CTH:YAG, Nd:YAG, Er:YAG and so on. 

Cylindrical lens is used to correct astigmatism in the optical system, and, in rangefinders, to produce astigmatism, stretching a point of light into a line. It is usually used in barcode scanners, objective systems and other optical systems.

Applications:

1 . Correcting Astigmatism

One of the main applications of cylindrical lenses is in ophthalmology, specifically, to correct astigmatic vision.  When a person presents astigmatic vision, it is usually the result of a corneal deformation. An astigmatic cornea will have different focal points at different axes. It is then possible to use a cylindrical lens to change the focal point of one of the axes to overlap the second one.

2 . Laser Line Scanning

This is a technique that is used to capture the  shape of a 3D object into a digital copy.  It is particularly useful in manufacturing, prototyping, landscaping, and architecture.  This scanning technique measures the deformation of a straight line created by a cylindrical lens when it is incident into a non-flat surface.  By using cameras and triangulation, it is possible to measure the changes in the shape of our laser line and therefore estimate the shape of the object that we are measuring.  If you would like to learn more about Laser Line Scanning please leave a comment.

3. Laser Scanning Microscopy

They are usually used in combination with acousto-optic deflectors, where the focal point of a variable lens (the acousto-optical elements) can change its position laterally without the use of movable parts.  The cylindrical lens corrects the image and helps focus the light spot onto the correct plane for laser scanning microscopy.
