Brand-New MS-2000 Non Flat Top Stage with Controller for Sale

We are offering brand-new MS-2000 Non Flat Top Stages for $7.500.00 for the following Microscopes:

  • TE/TI2000
  • IX71/81. It won’t work with IX73/83
  • IX70
  • DMI6000. It won’t work with DMi8
  • AV2000
  • TE300

Specifically designed to provide a high resolution, and highly repeatable, means of controlling the X and Y position of the microscope stage. All axes derive their precise control through the use of closed-loop DC servomotors employing high-resolution rotary encoders for positioning feedback. The MS-2000 XY stage utilizes crossed-roller slides, a high-precision lead screw, and zero-backlash miniature geared DC servomotors for smooth and accurate motion. The Z-axis drive also uses ASI’s proven line of closed-loop motor drives, each custom fitted to the microscope. The microprocessor-controlled MS-2000 control unit provides for RS-232 and USB communication with a host computer.


  • XY axis range of travel: 120 mm x 110 mm
  • XY axis resolution (encoder step): 22 mm
  • XY axis RMS repeatability: <700 nm
  • XY axis maximum velocity: 7 mm/sec
  • Max Recommended Load: 5kg

Preliminary plans for 3rd multi-immersion objective lens

We are going public with tentative plans for our third multi-immersion objective lens. By end-2019 we plan to finalize the design based on feedback, plus decide how large of an order to place for them (the larger the order the smaller the cost, but we have to be assured they will sell). So please get in touch if you are interested, and please give your feedback!  The current plan is to have them available late spring 2020.

This objective lens design was inspired by three use cases:

  1. Lattice light sheet or similar high-NA live cell light sheet imaging. It can replace the Nikon 25x/1.1 W objective which is commonly used but far from ideal for this application.
  2. Imaging cleared tissue with higher NA than any existing cleared tissue or glycerin objective. Working distance and field of view are relatively modest for this application but sufficient to be useful for some samples.
  3. Single-objective light sheet with a relatively long working distance.

Here is a brief overview of the preliminary specifications:

  • NA 1.05 in water, NA 1.22 in ECi or BABB
  • 48x in water, 56x in ECi or BABB (with 200 mm tube lens)
  • 0.5 mm diameter FOV
  • 3.05 mm working distance
  • designed for 1P light sheet (plan-corrected, optimized for visible)
  • 75 mm parfocal distance, M25x0.75 threads, 57° mechanical half-angle (fits in place of Nikon 25x/1.1w)
  • price $25k-$30k depending on production run size

Like our other multi-immersion objectives it features a curved first surface which allows it to be used in any dipping medium without a correction collar. Tentatively the chromatic correction is optimized for water and degrades somewhat in organic media, but we could change this before finalizing.  We hope to make it resistant to dipping in harsh organic chemicals like DBE and BABB like our other multi-immersion objectives but we aren’t 100% sure whether that will be possible yet (if that’s crucial to you please let me know); for sure in will work with water, glycerin, FocusClear, etc.

I’d love to talk in person about this lens if you happen to be attending SfN Oct 21-23, LSFM Dec 4-6, or ASCB/EMBO Dec 8-10. Otherwise please contact me by email for further details and to give your feedback. My “survey questions” include the following:

  • How would you use this objective lens? (e.g. lattice, cleared tissue, and/or SOLS)
  • Any specification you would like changed? How?
  • How certain would you purchase it within 2 years?
