• The LSM04DC is Ideal for 850, 1050 and 1315 nm Imaging Systems
• Designed to Match the Dispersion of the LSM04 Series Objectives
• Good Dispersion Compensation up to Second Order
• AR Coated for 800-1400 nm Wavelength Range
• Mounted in an Engraved SM1 Series Lens Tube

Thorlabs’ LSM04DC dispersion compensating block helps to compensate for dispersion up to second order. The LSM04DC is a single glass dispersion compensation block for our LSM04 scan lenses. The glass type and the thickness were chosen so that the dispersion matches the dispersion of the LSM04 series objectives. The LSM04DC is mounted in an engraved 1" long SM1-threaded lens tube and AR coated for 800 - 1400 nm wavelength range.
