The Global Laser Collimating Lens Market is likely to grow from USD 289 million in 2021 to USD 880 million by 2030, at a CAGR of 5.7%. Collimation is the process of aligning light or particles in a straight line. When it comes to light measurement, collimating guarantees that the light spreads as little as possible. To achieve accurate readings from devices like spectrometers, colorimeters, and light metres, the light entering the instrument should be parallel. As a result, collimating lenses are utilised in these instruments to ensure that correct readings are obtained. A collimating lens system typically consists of a tube containing one or more lenses.
