Monocular Research Microscope, Coaxial Focussing 45°

Quick Answer: The Monocular Research Microscope, Coaxial Focussing 45° is a single-eyepiece compound microscope with the tube inclined at 45° and coarse and fine focus on one shaft. This coaxial monocular microscope suits colleges and laboratories that want research-style focusing without a binocular head.

Research Focusing on a Single-Eyepiece Stand

Two features lift this model above the basic monocular: the inclined tube and coaxial focus. The inclined tube means the user looks in at an angle while the stage stays flat, which matters for wet preparations such as a hanging drop or urine sediment that would run on a tilted stage. Coaxial focus keeps the fine control under the fingers, so users working at high power make small corrections instead of reaching for the coarse knob.

It remains a monocular instrument. All the light goes to one eyepiece, so there is nothing to align between two eyes, but long sessions are more tiring than with a binocular head. A lab can keep a coaxial monocular for quick checks and a binocular model for extended scanning, matching each instrument to the length of the job.

Specifications

Applications

• Hanging-drop and wet preparations for bacterial motility, where a level stage matters
• Training in urine sediment examination in medical laboratory technology courses
• Checking stained smears in college microbiology practicals
• Undergraduate botany and zoology slide work in smaller labs

Care & Handling

• Before changing objectives, bring the fine control back to the middle of its travel; a fine focus left at its stop leaves no room to sharpen the next lens.
• Check each term that the clamp screw holding the inclined tube of the coaxial monocular microscope is tight, so the eyepiece cannot swing away from the user.
• After biological preparations, wipe the stage with a cloth moistened with 70% ethanol, then dry it.
• Leave the dust cover on between sessions.

Frequently Asked Questions

What is a hanging-drop preparation and why does a level stage matter?

A drop of culture hangs from a coverslip over the hollow of a cavity slide, so live bacteria can be watched swimming. If the stage tilts, the drop shifts and the organisms move out of the focal plane. An inclined tube lets the user view comfortably with the stage kept flat.

How is the Coaxial 45° model different from the Basic monocular?

It names two things the Basic listing does not: a tube inclined at 45° and coaxial coarse and fine focus. The single-eyepiece principle is the same.

Is monocular viewing brighter?

All the light from the objective reaches one eyepiece instead of being divided between two, so a monocular image can look brighter at the same light setting. In practice the light is simply adjusted to suit either head.

How should the fine focus be used at high power?

Bring the image roughly into view at low power, centre it, switch objective and then use only the fine control. At high power the depth of focus is so shallow that even a small turn of the coarse knob throws the image out of view or pushes the lens towards the slide.

Can a camera be fitted?

An eyepiece camera can replace the eyepiece for occasional images, though the user then cannot look through the tube at the same time. For regular documentation, a trinocular microscope with a separate camera port is more convenient.

What should be used to wipe the stage after biological samples?

A cloth moistened with 70% ethanol or another disinfectant suitable for painted metal, followed by a dry cloth. Keep disinfectant off the lenses, and dispose of slides made from patient samples as the lab’s biosafety rules require.
