This is description of this part:
Nikon TU Plan Fluor 20x/0.45 A ∞/0 EPI D OFN25 WD4,5 microscope objective.
This objective is primarily designed for reflected-light EPI microscopy in brightfield and darkfield, but it is also suitable for transmitted-light brightfield observation.
Nikon TU Plan Fluor objectives are frequently used for macrophotography and ultra-macrophotography. When combined with a Nikon tube lens (Nikon tube lens) or a Rodenstock Apo-Gerogon 210 mm lens, they provide outstanding image quality when connected to a camera.
Basic specifications of the Nikon CFI TU Plan Fluor 20x/0.45 microscope objective:
Manufacturer: Nikon
Manufacturer catalogue number: MUE42200
Marking on the objective: TU Plan Fluor 20x/0.45 A ∞/0 EPI D OFN25 WD4,5 MUE42200
Magnification: 20x
Numerical aperture N.A.: 0.45
Colour correction: Plan Fluor
Optical correction: infinity
Infinity system: CFI 60
Field number OFN: OFN25
Working distance WD: 4,5 mm
Cover glass: not required
Immersion: no - this is a dry objective
Operating mode in reflected-light EPI microscopy: brightfield (BF) or darkfield (DF)
Thread: M32
Compatibility with microscopes equipped with an M25-thread nosepiece: yes, by using the MXA23017 adapter or by replacing the nosepiece with the Nikon L-NBD5 or LV-NBD5 model
This objective is compatible with microscopes designed for reflected-light EPI microscopy and equipped with an M32-thread nosepiece, for example:
- Nikon Eclipse L
- Nikon Eclipse LV
- Nikon MM-400 and MM-800 toolmakers microscopes
This objective is also compatible with microscopes in which the M25-thread nosepiece can be replaced with an M32-thread objective nosepiece, namely the Nikon L-NBD5 or LV-NBD5. These include, for example:
- Nikon Eclipse E600
- Nikon Eclipse E800
- Nikon Eclipse 50i / 55i
- Nikon Eclipse 80i / 90i
- Nikon Eclipse Ci
- Nikon Eclipse Ni
A suitable reflected-light EPI illuminator can also be installed on these microscopes to take full advantage of the capabilities of this objective.
For other Nikon CFI60 microscope models, for example:
- Eclipse E200
- Eclipse E400
- Eclipse Si
- Eclipse TI / TE / TS series inverted microscopes
the MXA23017 adapter can be used, allowing M32-thread objectives to be mounted in an M25-thread nosepiece - therefore the objective presented here can also be used.
What is this part needed for?
- if you need such an objective for brightfield or darkfield EPI observation on a Nikon microscope
- if you need a high-quality objective for macrophotography and ultra-macrophotography
