Pressure measurement is the analysis of an applied force by a fluid (liquid or gas) on a surface. Pressure is typically measured in units of force per unit of surface area. Many techniques have been developed for the measurement of pressure and vacuum. Instruments used to measure and display pressure in an integral unit are called pressure meters or pressure gauges or vacuum gauges. A manometer is a good example, as it uses the surface area and weight of a column of liquid to both measure and indicate pressure. Likewise, the widely used Bourdon gauge is a mechanical device, which both measures and indicates and is probably the best known type of gauge. Applications ♦ Injection Molding Device, hydraulic ♦ Machine building and plant construction ♦ Heating and air-conditioning technology ♦ Fire sprinkler systems, compressor Special features ♦ Design per EN 837-1 ♦ Nominal size 40, 50, 63, 80, 100 and 160 ♦ Scale ranges up to 0 ... 1000 bar

customized trial set clear optical lens instrument plano-concave lens transparent optical lens Rod Lenses are a special variant of cylindrical lenses. They are complete rods where the light passes through the sides of the rod and focuses a line. Rod lenses have an outside face that is polished and the ends ground. The table below gives angular lengths of the line for a 1mm diameter laser beam. Typical uses for rod lenses would be to generate a line image from a circular laser beam. Knight Optical supply rod lenses both mounted and unmounted. Our mounted rod lenses can be easily attached to laser heads and then easily rotated into the correct orientation.
