The smallest rod lenses (micro rod lenses) have been produced by Photonchina for customers at home and abroad

June 2, 2021

Photonchina produces the smallest rod lenses for customers at home and abroad. Micro rod lenses: 0.5-1.8mm diameter, 1.0-25mm length, with one end of designated curvature radius and another end of arbitrary angle. Both ends of arbitrary radii or angle are also available. Highly customized products for a wide range of applications from medical device, fiber communications, optical display and surveying equipment.

What is more, we can provide unique rod-shaped glued lenses by combining special gluing/cementing technics and edging skill. These glued/cemented rod lenses subassembly can be made of up to four single micro rod lenses with various combination. Rod lens assembly systems are able to provide images with greater brightness, contrast and color reproduction than conventional lenses.

Rigid endoscope, for instance, which usually has a series of high-resolution optical glass rod lenses, can be forward viewing (0 degrees) or angled (10–120 degrees) to allow visualization out of the axis of the telescope and increase the FOV by rotating the instrument. The optical quality of lens-generated images of rigid endoscopes still surpasses that of the fiber-optic or digital images produced by flexible scopes.

High performance optical coatings for rod lenses are provided.

Optical glass material NBK7, N-SF11 from Schott, Corning 7980 etc, are all available.

About Photonchina

Photonchina is a leading manufacturer of micro rod lens and quartz waveplate products in the world.

In terms of micro rod lens, Photonchina capacity has now reached as small as 0.5mm in outer diameter and 25mm in length, with any radius of curvature that can be made. Micro rod lenses are available with flat, plano-convex, plano-concave, double convex in shape. This rod lens has excellent eccentricity and clear aperture index.
