Nikon TMS Inverted Binocular Microscope

Nikon TMS Inverted Binocular Microscope

Price: 740.00 (Excluding VAT at 20%)

The TMS is one of the classic Nikon microscopes that were built specifically for the examination of tissue cultures. This is a very good example of the TMS and is all original. x10 wide field eyepieces set well above the stage plate. The microscope has rheostat controlled 6v 20watt halogen illumination. This TMS has a good turret of objectives that are all 160mm tube length.
x40 with coverslip correction (n.a. 0.55)
x10 (n.a. 0.25)
x20 (n.a. 0.40) with coverslip correction
x40 phase contrast DL (n.a. 0.55)

This is an excellent microscope at a very realistic price considering its heritage

Nikon Phase Contrast Trinocular Microscope (2192)

Nikon Phase Contrast Trinocular Microscope (2192)

Price: 729.17 (Excluding VAT at 20%)

On 4 November 1953 Frits Zernike was awarded the Nobel Prize for Physics for his invention of the phase contrast microscope. This precipitated the major microscope manufactures to produce instruments that could achieve this effect. There were copyright issues involved in this as both Leitz and Nikon of course realised. This microscope is truly a collectors item. It is Nikons early attempt to provide a microscope that involved the phase contrast mechanism at a price that was affordable. In addition, they very cleverly involved polarisation.

Traditionally phase contrast requires different objectives with retardation rings within the lenses of the objective (usually made from silver) that match with phase rings in the condenser. This system on the other hand has a phase contrast condenser with appropriate phase rings and a bright field setting. Then the microscope has a slider mechanism that has a series of phase rings that can introduced into the optical path of the standard bright field objectives. Put simply this is a very clever idea. The standard bright field objectives can be allowed to function normally and then with the slider mechanism built into the optical path, phase rings could be introduced as required. It has to be said that it is difficult to understand why this system was not carried forward. However, this means that the microscope remains a very important collectors item.

Nevertheless, way back in the late 1960's Nippon Kogaku (Nikon) introduced the "polanret" type phase system of their own, intended for use on their Model "S" series of stands. However, unlike the later AO system the Nikon system was simple, compact and rather affordable. It also distinguished itself by creating user-controllable interference colours in the phase images! Apparently just to ensure that potential users had no idea what it was, they called their marvellous new creation, Nikon "Interference Phase Contrast" (or, more simply, "IPC")

This particular unit has the benefit of having an LED conversion system which extends it as a functional unit for the years to come, and its value will continue to rocket as a collectors item over the coming years.

Nikon Optiphot 2 Binocular (2236)

Nikon Optiphot 2 Binocular (2236)

Price: 383.33 (Excluding VAT at 20%)

The Nikon Optiphot series were considered amongst the best and most durable of microscopes and were principally responsible for elevating Nikon into prominence as one of the leading manufacturers of quality microscopes. The Optophot 2 was introduce in the early 1990's and is still widely used professionally today because of its durability. It is unmistakable because of the leatherette wrist supports on either side of the base. This is a binocular version with its original EPlan objectives in very good condition: x4 (0.10), x10 (0.25), x20 (0.40), x40 (0.65) and x100 oil immersion (1.25) couples with CFWN widefield x10/20 eyepieces.

The Kohler illumination system has an external light box housing a 12 volt 100 watt lamp. The front of the stand has the brightness control system that responds with an LED line which reflects the lamp brightness and there is also a photography override button to provide optimum illumination.

The 'leatherette' inserts in the base were design for wrist comfort when using the focus controls, as a result watches and bracelets do tend to leave their marks although on this unit they are quite reasonably preserved. As would be expected there are a few small chips to the paint enamel on the base. A Nikon classic at a very good price.

Nikon Long Arm Stereomicroscope

Nikon Long Arm Stereomicroscope

Price: 437.50 (Excluding VAT at 20%)

This is an excellent opportunity to acquire a quality stereomicroscope that was built for training purposes. Currently the use of digital imaging has allowed collective viewing with microscopy. However, the double head microscope allows both the 'student' and the 'teacher to manipulate the specimen at the same time. The allows the 'not like this' but 'like this' approach which has great value. This unit has a trinocular port which allows digital imaging in addition. The magnification range of the microscope is x6 to x40 with the x10 wide field eyepieces. There is a slider lever which allows an imaging system to be employed at will. This is a strong heavy based microscope in good condition - the base has been re-sprayed at some point recently.

Nikon Binocular Head

Nikon Binocular Head

Price: 95.83 (Excluding VAT at 20%)

A Nikon binocular head complete with Nikon eyepieces Fits the older style N series microscopes. Finished in black and in good condition. Interocular and dioptric adjustments. x10 wide field eyepieces with integral eyecups.

Nikon Labophot Phase Contrast Binocular (2377)

Nikon Labophot Phase Contrast Binocular (2377)

Price: 416.67 (Excluding VAT at 20%)

The Labophot series were date from the same period as the Optiphot, but has a slightly smaller stand and an internal lamp housing system. This unit has a full Zernike phase contrast system and is optically in first class condition. It has been well used in its lifetime and the base does show signs of this with several chips to the enamel paint. Nevertheless, it is a fine optical microscope. The Zernike phase contrast condenser has a bright field position and the usual adjustment system for the phase rings. The original Nikon objectives are x4 (0.10), x10 (0.25) phase, x20 (0.40) phase, x40 (0.65) phase and x100 (1.25) phase oil immersion and are couples with CFW x10 eyepieces.

The Kohler illumination system has an internal 6 volt 20 watt halogen lamp unit with a wheel system behind the field lens that controls the field iris diaphragm. Phase contrast Labophot's do not come up that often

Nikon Slide Marker (2227)

Nikon Slide Marker (2227)

Price: 58.33 (Excluding VAT at 20%)

This is an ingenious device for marking areas of interest on coverslipped slides. Often used in path labs for marking areas of tissue or cervical smears for further discussion. It has a standard RMS screw thread at one end so that it can be fitted to the objective turret of any microscope. At the other end is a felt ring impregnated with black ink which is spring loaded so you can lower it onto the slide and rotate it to leave a black circle over the interesting part.
