Specification Charts & Notes
Thrust or torque is a function of speed. The values given above are maximums. These values cannot both be achieved simultaneously (i.e. at maximum speed, the unit will not produce maximum thrust).
Error
Long duration compensation for thermal drift on a Nucleus® microscope.
A Nucleus® microscope equipped with an HL04 laser autofocus module can effectively maintain focus despite thermal drift induced by changes in ambient temperature. The blue line tracks the position of the focus stage as it actively compensates for thermal drift caused by the air conditioning.
Transmission plot of 785 nm notch filter pre-installed in MJB25C-F1
Transmission plot of 785 nm notch filter pre-installed in the required MJB25C-F1 junction block. The notch filter will block key wavelengths for the Cy7 fluorophore, so Cy7.5 should be used instead.
