OVERVIEW
Micro Rod Lenses
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.
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.

Applications
Designed for use in a variety of laser and imaging systems, Photonchina also manufactures rod lenses with the circumference optically polished and ground on both ends. A range of these micro size rod lenses are integrated into a host of OEM applications. Its optical performance is similar to a cylinder lens. Collimated light passing through the diameter of the rod lens will be focused into a line. N-BK7 and UV Fused Silica substrates are available for a variety of UV, Visible and NIR applications.
KEY FEATURES
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.
