A few of the specifications:
- 10X N.A. 0.30 Air Plan-NEOFLUAR SN 420340-9901
- 20X N.A. 1.00 Water Plan-APOCHROMAT DIC VIS-IR (which is my favorite lens for imaging tissue)
- 20X N.A. 0.75 planapochromat air
- 25X N.A. 0.80 Oil-Glycerol-Water DIC (UV)VIS SN440842-9870
- 63X N.A. 1.40 Oil Plan-APOCHROMAT DIC SN 420782-990
People often ask, what about 100X? The numerical aperture defines the resolution, not the nominal magnification. The 63X N.A. 1.40 lens has the same spatial resolution at the
100X N.A. 1.4 lens when using effective optical zoom by scanning a smaller field slower or collecting a large number of pixels. It has benefits of being able to scan a larger field of view, longer working distance, and superior light collection.
- Antivibration table: Newport ST Series with autotune damping and I2000 series legs 1500 mm X 1800 mm X 203 mm (71 X 59 X 8 inches), 805 lbs not including the legs.
- All fluorescence detectors PMTs (3 internal for confocal and 5 external for multiphoton); additional transmitted light detector.
Please note, this scope is not good for Alexa Fluor 350 and 594. 350 will not work at all. High concentration 594 will provide signal but is excited inefficiently by the 543 nm laser.
Please review which fluorescent probes work with this microscope before purchasing for experiments.
Using the Mai Tai laser, the lowest practical wavelength is approximately 760 nm.

Three internal detectors with user selectable spectral ranges from a little below 405 nm to to 740 nm. These may be used for standard confocal or for multiphoton. According to the software controls, the internal detectors collect up through 758 nm. However, testing with reflection mode with the longest wavelength physical gate, collection is practical only to 740 nm. After 740 nm collection intensity falls rapidly and is not detectable above 750 nm.
Standard Filters in External Detectors for nondescanned multi-photon. These filter blocks are easy to change if users have special needs and the blocks are purchased or borrowed.

Recommended alternative to water for using water immersion objectives.
General Confocal Best practices:
- The pinhole is what makes the confocal a confocal. Always set at 1AU (which means 1 Airy unit) or smaller and reset this each time you change lenses.
If you are opening it for imaging fixed samples, you should go use a widefield fluorescence scope instead.
Except in exceptional live cell imaging where you understand that you are not being confocal, this is NOT AN ACCEPTABLE WAY TO MAKE IMAGES BRIGHTER. You won't hurt the instrument, but when you write your methods, you won't be accurately describing your microscopy as "confocal".
- Offset. Always use at 0 or 1.
Other numbers are wrong.
- Digital gain. The preset is 1. Leave it there.
- Example of scan speed, averaging, filtering and noise click here.
Always save files as LSM or CZI. These files can be opened directly into inmage analysis software. These files retain instrument settings, channel integrity, bit depth, and spatial scale that may be necessary for image analysis.
If you save files as TIF or other formats, the inetgrity of of color channels may be lost and you will have no metadata regarding instrument settings and spatial scale.
