SM2L30 In Stock

The SM2L30 by ThorLabs is a high-quality SM2 lens tube that provides an efficient and convenient solution for building compact optical assemblies. With its stackable design and direct interfacing with all SM2-threaded (2.035"-40) components, the SM2L30 offers unparalleled flexibility for constructing complex optomechanical assemblies.

Designed to be compatible with 60 mm cage assembly systems, the SM2L30 enables the creation of a compact assembly with light-tight beam paths, allowing for greater precision in optical applications. This lens tube has a length of 3.03" (77.0 mm) and an internal thread depth of 3.00" (76.2 mm), making it an ideal size for a wide range of optical applications. The SM2L30 features a simple yet effective retaining ring system that securely separates and holds optics in place. Retaining rings can be positioned at the desired depth within the lens tube using a compatible spanner wrench, ensuring precise and repeatable positioning of optical elements. Additionally, this tube is compatible with a SM2RR retaining ring and can be used to house one or several optical elements, providing further versatility in optical system design.
