Dispersion Compensators for Scan Lenses

Features

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 # SM1L01) 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.

Hi, it is not a feedback regarding the product, but shipping information. I have made an order of a CLS-SL through my agent company, and expected a fast shipping based on your website's information (3-5 days). But, to my surprise, I got a call from the company saying it will be available 2-3 months later. Please let me know. Thank you.

Response from Tim at Thorlabs: This scan lens is suitable for use with an Olympus 180mm tube lens. The ITL200 Nikon tube lens is used in their research grade microscopes and can be used with Olympus objectives as well. However, we must be aware that magnification will not be what is noted, but slightly higher. As Nikon uses a 200mm focal length tube lens as opposed to this and standard Olympus design of 180mm focal length tube lenses, the magnification will be 200/180 times greater.

I would like to know if this scan lens would also be suitable for use with Olympus 180 mm tube lens and olympus objectives. I imagine that it is not advisable to mix the Nikon tube lens with our Olympus objectives.

Hello, I'd like to model to the LSM03-VIS in my optical design software, but it can only import ZMX files, not ZAR files. Is there any chance you could send me either 1) a ZMX version of the prescription info for the LSM03-VIS, or 2) simply a text version of that info, specifically the glass types, that I could enter by hand in my software? I can see from the STEP model what the geometry of the lenses is, but I don't know what kind of glass each one uses. Thank you!
