We can manufacture various shape and special material optical lens.The coating for lenses not only the normal BBAR coating,but also including dichroic coating and super broad band antireflective coating.
Plano-Convex (PCX) Lenses have a positive focal length, making them ideal for collecting and focusing light in imaging applications. They are also useful in a variety of applications involving emitters, detectors, lasers, and fiber optics. Coated versions have optimum light transmission. Available in a wide variety of diameters and focal lengths.
The coated lenses can be utilized in a host of optics and photonics applications, including biotech instruments such as DNA sequencers and polymerase chain reaction (PCR) testing platforms.

How should the plastic pelletizing extruder control the head pressure?
In order to reflect the extrusion of the plastic pelletizing extruder head, it is necessary to check the head pressure during extrusion. Since the domestic plastic pelletizing extruder does not have a head pressure sensor, it is generally a substitute for the measurement of the thrust after screw extrusion. The measurement of the head pressure, the screw load meter (current meter or voltmeter) can correctly reflect the extrusion pressure.
The fluctuation of extrusion pressure is also one of the important factors that cause the extrusion quality of plastic pelletizing extruder to be unstable. The fluctuation of extrusion pressure is closely related to the extrusion temperature, the use of cooling device, and the length of continuous operation time.
When an abnormal phenomenon occurs, the rapid elimination that can be eliminated, the reorganization of production must be decisively stopped, not only can avoid the increase of waste, but also prevent accidents.
