- Provide Up to Second Order Dispersion Compensation
- Two AR-Coated Options Available
- Mounted in an Engraved SM1-Threaded Lens Tube
These single glass dispersion compensation blocks are designed for use with our LSM scan lenses. The glass type and the thickness were chosen so that the dispersion matches the dispersion of the LSM scan lenses. The dispersion-compensating block is meant to be placed in the reference arm before the mirror, while the objective sits in the sample arm. Thus, there is an identical amount of dispersion in each leg of the interferometer. All of these dispersion compensators are mounted in an SM1-threaded lens tube (item # SM1L10) engraved with the item number.
Thorlabs offers two versions of these compensators, each with a different AR coating. The LSM03DC-VIS compensator has an AR coating for the 400 – 700 nm wavelength range, and is designed to be used with the LSM03-VIS scan lens. The other compensators sold on this page, LSMxxDC, are AR coated for the 800 – 1400 nm range, and are designed for use with our LSMxx and LSMxx-BB scan lenses.
