Plano Concave Cylindrical Lens
Plano-concave cylindrical lenses provide uni-axial negative imaging for anamorphic beam expansion and a wide range of applications.Plano-concave lens is the most common item used for light projection and beam expansion. Coated with antireflective coatings, lenses are used in various optical systems, lasers and assemblies. Catalog items list consist of most common diameter and focal length uncoated lenses made from BK7; UVFS; CaF2 and ZnSe.
Plano Concave lenses have one flat and one inward curved surface. Plano Concave lenses have a negative focal length and are used for image reduction or to spread light.
Rod Lenses are polished on the circumference and ground on both ends. Optical performance is similar to a cylinder lens.

What is the operation method of the Relief Sprayer? Henan Yuli sprayer manufacturers detailed about the operation method of Yuli sprayer.
1. First, check whether the joint fastening of the spraying machine is correct and reliable.
2. Start the motor and check if the direction of rotation is correct.
3, check the rubber seal and tighten the force, first hand lock the nut on the device until it is tight, and then use the plate on the hand tight 2-3 laps until the rubber seal plate does not leak.
4, open the air valve, demolition of the feed pipe pressure is about 0.5Mpa, no pressure on the rubber plate leaked, indicating that the degree of fastening is just right.
5, spray hand-held spray gun, facing the wall, gun head to the injection site to maintain the distance of 0.8-1.2m, ready for injection operations.
6. Before the operation, open the main valve first, and open the upper air valve to 1/3 turn, adjust the downwind to an air pressure of about 0.6-1Mpa.
7. The sprayer opens the nozzle water valve and flushes the surface of the prewet rock.
8. Start the spraying machine. The charging workers add concrete materials into the hopper of the spraying machine and incorporate a quick-setting agent. When loading, the material should be kept continuous and uniform, and concrete spraying operations should be started.
9. When spraying, it is necessary to make up after the first uniform and then the double spray to meet the design requirements.
10. When spraying hand-sprayed concrete, the nozzle shall be perpendicular to the spray surface as much as possible, and it shall be evenly moved with a half-circle of a spiral. The diameter of the spray ring is approximately 200-300mm, and the width of each spray is preferably 1.0-1.5m.
11. When the concrete is sprayed, there is an assistant who assists the lighting and signal from the side at a distance of 5m from the injection site.
12, stop the injection, to stop loading, first stop the spraying machine, until the remaining material in the feeding pipe is blown out, no material is ejected, the water valve can be closed, and finally the total wind valve is closed.
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.Designed for use in a variety of laser and imaging systems, these components are available in a range of micro sizes for
integration into a host of OEM applications. Custom sizes, variations in polishing/ ground surfaces and additional coatings are
available upon request, please contact our Sales Department for details.
