The LS-30 Series and LS-300 Series of Laser Beam Shutter are designed to form a part of a high-integrity safety. They are among the best-selling products of Lasermet and serve as essential components in laser safety systems and laboratory environments.
Before we explore the differences between the LS-30 and LS-300, it is helpful to understand their similarities. Both beam shutters share the same functionality with the purpose of handling laser beam safely and efficiently. It is available in single and dual channel beam apertures. The dual channel laser beam shutters are SIL-rated and meets Safety Integrity Level to IEC 61508-1 and Performance Level ’e’ to EN 13849-1. They are typically supplied with stainless steel blades but when necessary or preferred can be factory fitted with ceramic, mirror and copper blades.
What is the difference between the LS-30 and LS-300 Series of Laser Beam Shutter?

The LS-30 Series features a spring-loaded shutter blade, allowing it to be mounted in any orientation. This design provides full control of blade movement, even when installed upside down. With an aperture of 16mm it is well-suited for applications involving small beam diameters. Additionally, the LS-30 Series can be integrated into pre-existing systems through its OEM variant. Its compact design and flexible mounting options make it one of Lasermet’s most popular products.

In contrast, the LS-300 Series features a motor-driven blade and is designed for laser beam paths that travel horizontally. It offers larger aperture options—50 mm, 75 mm, and 100 mm—allowing users to select the most appropriate size for their application. This series is particularly recommended for high-powered lasers and applications involving larger beam diameters.
Lasermet’s shutters are manufactured using high quality materials ensuring its longevity and capabilities under operation. They undergo rigorous testing to achieve a high standard of performance. As part of its commitment to continuous improvement, Lasermet is also developing additional aperture sizes to accommodate a wider range of laser beam applications.
