Attach The Condenser; Attaching The Optical Module To The Universal Condenser - Nikon Eclipse Ni-U Instruction Manual

13

Attach the condenser.

Tool: Hex driver (2 mm across flats)
(1) Turn the coarse focus knob until the substage is
brought to the upper limit.
(2) Turn the condenser focus knob until the condenser
holder reaches the bottom.
(3) Fit the round dovetail of the condenser to the
condenser holder so that the Nikon nameplate faces
front and tighten the fixing screw of the condenser
holder with a hex driver.

■ Attaching the optical module to the universal condenser

The turret has one empty hole and six optical module mounting holes. The empty hole is address 1 and the
optical module cannot be attached here. The desired optical module can be mounted in the mounting holes of
address 2 to 7.
Tool: Hex driver (2 mm across flats)
• DIC module on the condenser (required for differential interference contrast microscopy)
There are DIC modules [D-C DIC N1 DRY], [D-C DIC N2 DRY], and [D-C DIC NR DRY]. Select the DIC
module appropriate for the objective. (See following table.) If the combination is not correct, differential
interference contrast image cannot be obtained or the contrast decreases significantly.
To support for particular purposes, module for higher contrast or resolution are available. Note, however,
that in principle the contrast contradicts the resolution of the differential interference contrast image (the
higher the contrast, the lower the resolution).
• PH module (required for phase contrast microscopy)
There are PH modules [D-C PH-1], [D-C PH-2], and [D-C PH-3]. Select the PH module with a matching PH
code with the PH objective.
• Dark field module (required for dark-field microscopy)
The dark field module [D-C DF] can be used with any objective with a numerical aperture (NA) of 0.7 or
less. Note, however, that 2x and 4x objectives are not supported.
• 2-4x auxiliary lens (required for low magnification bright-field microscopy)
2x and 4x objectives can only be used for bright-field microscopy. In this case, select a 2-4x auxiliary lens.
Two types of 2-4x auxiliary lens are available with different diameter and different condenser turret
attachment address: 2-4x auxiliary lens [NI-CAL N1] and 2-4x auxiliary lens [D-C 2-4x].
