  <p>
Coupletech supplies various of lenses for different application, including laser cavity, laser beam shaping, image transmission, optical measurement, optical equipment etc. So we can supply different quality standard for different application. Customer mostly to use high quality for laser, imaging, optical measurement application, and low standard quality for low cost and large quantity application.

Plano-convex lens: Positive focus length. Most suitable where one conjugate is more than five times the other, e.g. in sensor application or for use with near collimated light.

</p>
<p>
Double-convex lens:&nbsp;Most suitable where the conjugates are on opposite sides of the lenses and the ratio of the distances is less than 5:1, e.g. as simple image relay components.

</p>
<p>
Plano-concave lens:&nbsp;Negative lens with the form most suitable where one conjugates is more than five times the other, e.g. producing divergent light from a collimated input beam.

</p>
<p>
Double-concave lens:&nbsp;Negative lens with the form most suited to producing diverging light or a virtual image, where the input light is converging.

<p>
Meniscus&nbsp;Positive lens:&nbsp;The lens may be used to increase the numerical aperture of a positive lens assembly, without an undue increase in the aberrations.

</p>
<p>
Meniscus&nbsp;Negative lens:&nbsp;The best lens form where one conjugates is relatively far from the lens or where both conjugates are the same size of the lens.

<p>
Cylindrical lens:&nbsp;
</p>
<p>
Used to provide focusing power in one section only. For illumination or detection of light from line sources. Also used to anamorphic compression of beams and images.
