Product Description

Thorlabs LA8126-E Mounted Achromatic Lens

The Thorlabs LA8126-E is a precision-mounted achromatic doublet lens designed to minimize chromatic aberration across a broad wavelength range. With a 100 mm focal length and 1/2-inch diameter, it is ideal for laser beam manipulation, imaging systems, and general lab optics where color correction is important.

Key Specifications:

• Focal Length: 100 mm

• Lens Diameter: 1/2 inch (Ø1/2″)

• Lens Type: Achromatic Doublet (N-BK7 & SF5 glass)

• Mount: SM05-threaded (0.535″-40) rotating housing

• AR Coating: MgF₂ coating on both sides (350 – 700 nm)

• Effective Focal Lengths: f = 100 mm (at 587.6 nm)

Applications:

• Laser beam collimation and focusing

• Multi-wavelength imaging systems

• Telescope and microscope objectives

• General-purpose laboratory optics with reduced chromatic error
