The terms water meters and flow meters can be used interchangeably, but there is a key difference between them. Whilst all water meters are flow meters, not all flow meters are water meters. Commonly applied in the domestic environment for devices used to determine your water bill, water meters measure the total amount of water that passes through them.

You may have heard the latest information from 3M® that they will exit from the manufacturing of Cleaning solvents in the near future. If you are a current 3M® cleaning solvent product user you will need to start to find 3M® alternative solvents. Find out what steps you have to take below…

Optical Surfaces Ltd is a leading producer of large diameter aspheric lenses used as critical focusing optics in high-power laser research.

Aspheric lenses provide a cost-effective way of reducing the number of optical elements in a focusing system thereby making them ideal for low f-number, high throughput laser applications. Beneficially also a correctly formed aspheric lens surface may cancel or control spherical aberration. As a result, more laser energy can be concentrated into a smaller area.
