The CLS2-SL-F70 is a large field of view achromatic scanning lens designed for broadband laser scanning imaging applications. As an upgrade over the previous CLS-SL-F70 model, it features extended wavelength coverage and increased light collection capability.

Extended Wavelength Range: Supports 370–1100 nm, covering UV, visible, and near-infrared bands, ideal for multicolor fluorescence, confocal, and multiphoton microscopy.Increased Entrance Pupil Diameter: Enhanced to 5 mm, accommodating higher laser power levels and improving signal-to-noise ratio and imaging sensitivity.Optimized Focal Length: Effective focal length (EFL) of 70 mm, well suited for common scanning modules and tube lens systems.Standard Mechanical Threads: Equipped with SM2 (2.035″-40) external threads on both ends, enabling direct integration into custom laser scanning setups or standard optical platforms with excellent mechanical stability and compatibility.

Recommended System Configuration

The CLS2-SL-F70 is recommended for use with the LENSTEK TTL-200MP tube lens and high-quality objective lenses to build a complete scanning microscopy imaging path, offering both high resolution and system flexibility.
